Horrific reactions to water and food during refeed after 7WF -> 7DF (WARNING to everyone to take Dry Fasting seriously)

Post by bundfalke »

Hello Yannick, i am creating this post as i didnt find another way to contact you as soon. The next 15-minute free consultation is at the 12th december.
On (day 3) i developed an extreme reaction to around 300ml of water.
Update: Now that i remember correctly, i developed this reaction to water even on the first day. When i sipped my water just a tiny whee bit too fast, i got this rush of symptoms, but it only lasted for around 10 minutes. During the first day i didnt think much of it.

I also want to say i am a mentally very strong person and im able to endure alot. But this has me brought me down to my knees. I can tolerate agony only for so long until i am broken.

These symptoms didnt subside. I stopped eating and drinking, but they kept on. Because of how severe the symptoms were, i researched extensively. It made me believe i drank too much water and was developing a brain edema (possible after extended Dry fast). I went to the hospital 6 hours later to get myself checked (symptoms still there)
A CT scan of my head and my blood test was good (blood tests below)

I went home feeling better. I drank 100ml water slowly and got the same symptoms immediately but on a lesser scale.
I was able to eat a little with no issues it seems.

My refeed journal day by day:
- Basically your variation of the filonov protocol the first 3 days with slight adjustments in amounts and types of foods.
- Yannicks refeed/scorch from day 4 onwards
Day 1:
- 100ml of low fat kefir,
- 2 liters of water (teaspoon, sipping) slowly throughout the day,
- 300mg magnesium glycinate, 600mg potassium chlorid
- 0.2g salt from the kefir

Day 2:
- Same as day 1 but with:
- 200ml kefir
- A little amount (maybe 150g, its a soup) of cooked buckwheat, white rice, lentils, broccoli, carrots, potatoes. Cooked for 3 hours, eaten very slowly (over an hour)
- 1.5 liters of water
- around 0.4g salt from foods
- So far no issues at all. Little urine but lighter in color

Day 3
- 300ml of nettle tea at 12:00 and around 300g of Buckwheat/broccoli/carrots/brown rice/potatoes soup, eaten/drinken faster than usual (in 20 minutes?)
After 15 minutes following happens:
- Extreme dizziness, that gets better when i stand up
- slightly nauseous
- hot flashes
- heart racing
- Strong sense of anxiety (never had anxiety in my life)
- Difficulty to think and talk
- Head pressure around my entire scalp


Day 4:
Overall: 300mg magnesium, symptoms under control because i barely ate and drank this day
- 12:00: i eat 1 pear, 8 grapes and a sip of nettle tea and the same thing happens, mildly severe.
- ate 2 tabs of active charcoil in case of herxheimer theory
- 16:00: Still reacting to last "meal". Now: 1 sip of my soup, immediate reaction after 2 minutes, extreme sense of anxiety and hot flashes, heart racing, dizziness (should be impossible after 2 minutes)
- Overall: faster and more severe reactions to less intake
- 18:00
- Went to hospital, symptoms slowly got better over 4-5 hours (no food/water intake).
- 23:00
- Come home, sip a little bit of water and get instant reaction

Day 5:
Overall: symptoms progressively getting worse and worse through the day
- 11:00: Drank 100ml of nettle tea in the morning, medium strong reactions as always (dizziness, hot flashes, anxiety).
- 13:00: still suffering due to that 100ml, thinking about turning this refeed into a water fast. Urine and stool have become more
- 14:00:
-drinking water with a teaspoon and letting it sit in my mouth increases the symptoms to unmanagable levels, unable to take in any amount of water now.
- last time i vaped
- 17:00:
- dizziness and anxiety persist, no matter my posture,
- trying to drink electrolytes (magnesium/potassium + others)
- new symptoms: skin is crawling everywhere, body feels like im plugged to a big battery. Changed vision that makes me think im on drugs and are giving me mental breakdowns (cant take it anymore). Very close to taking benzodiazepams in order to stop this.
- 19:00:
- Somehow able to tolerate plain water. Still suffering, still extreme symptoms, but symptoms dont increase this time after drinking water
- Drinking water mixed with potassiumchloride increases symptoms in seconds???
- eaten some of my fruit soup, 2 bananas and some fruit juice. No immediate increase in symptoms, still suffering though
- used the chance to take cetrizine, aspirin, l-theanine, NAC, multivitamin (neither helped directly)
- happy i was able to eat food and drink water with no reaction.
- cannot take the psychological horror of the visual and auditory changes anymore, took 0.1mg of alprazolam (benzo)
- 19:30
- Urinating and pooping a healthy amount from water and food intake
- cannot feel the benzo yet,
- took 100mg of Vit B1 as per user post
- 20:00
- Feeling calmer, trying to figure out if it was the Vit B1 or the benzo. Took another 100mg Vit B1
- Nervous System feels like it was just burned through after 6+ hours of suffering. Extreme stress are probably causing visual changes
- Skin is still crawling, still feel drugged like by psychedelics, running around in circles. Heart has settled tho (benzo?)
- Very scared i have to keep taking Benzos in order to endure this. Scared they will stop working. Scared of dependency. Scared im making things worse by using them
- 20:30
- Vagus nerve and breathing exercises in order to calm down more, trying to prevent myself from taking more benzos
- skin stopped crawling/needling (benzo effect probably)
- good sip of water, still no reaction
- Most patterns/reactions do not mean much now that ive taken the benzo, exercises seem to help though
- ate a banana and a piece of watermelon too fast, unfortunately got flush of anxiety, heart racing and dizziness (despite benzo)
- overall feel better, trying to figure out how to sleep tonight and how to overcome next day. Scared of the next day, scared of taking more benzos.
- still trying to determine wether a water fast would be better for me right now
- Note: urinating alot and very well this day
Notes for this day: Reaction to water seems to always be there. Once the symptoms set in after drinking water, they stay. Drinking more water (very slowly) doesnt make them much worse, they just stay.


Day 6:
- 09:00:
- unfortunately woke up with persisting anxiety and crawling/tingling skin and slight visual effects. Body is under stress from so much suffering
- these symptoms are distinct from what i get after drinking water. They are more like symptoms of my body being under stress too long
- sipped 100ml of water slowly and got flush of symptoms 5 minutes later (hot flashes, extreme dizziness, heart racing)
- devestated im going to keep living like this
- 10:00:
- took ashwagahnda, l-theanine, NAC, magnesium Glycinate
- drank 200ml slowly since 09:00 and feelings of anxiety, hot flashes, skin tingling are intensified each time i sip. Mental breakdown and crying
- 11:00:
- at my doctor, asking for help while in tears, trying to explain what i did and trying to give as much information as possible
- doctor is putting me in a room and giving me IV solution (as im barely drinking water)
-as expected 0.9% salt made it much much worse. Blood pressure dropped to 100/60, mouth extremely dry felt like i was about to pass out
- Salt will spiral me down into emergency, big no no
- aborted the IV solution as there was no solution without sodium
- drinking plain water slowly made me feel better. (Better as in, i dont feel like collapsing anymore, still suffering obviously
- 13:30:
- Doctor did some blood tests and urine tests, gave me a letter so i can visit the hospital, said i should keep doing whatever is making me feel better
- results come in the next days
- Staying at my doctors so they can watch over me while my body calms down
- 15:30:
- blood Pressure now 110/70, blood oxygen 97%, HR 100
- leaving doctors, trying to ride my scooter but i cant. Broke out in tears as i feel so lost and helpless. Pushing my scooter home for 30 minutes
- can barely walk, dizziness too strong
- up until now, extremely out of breath and barely able to talk, suffering more than yesterday in total
- 16:00:
- at home now for 30 minutes. Pure Potassium Chloride arrived today. Mixed 2g (1g pure potassium) with 300ml water, sipping very slowly
- First time able to take in potassium without anything else
- took 150mg Mag Glycinate, 100mg B1, NAC, L-Theanine, multivitamin
- 16:30:
- Big Rush of calmness and my Nervous System seemingly calming down. Almost unpleasent but symptoms of skin crawling are less. Potassium working
- HR slowed down, overall feeling better.
- 17:15
- unfortunately getting rushes of increased symptoms from sipping potassium water. Potassium still effective though
- took another B1 and Mag Glycinate
- 17:30:
- still sipping potassium water, dry mouth gone
- ate a banana and drank some fruit/coconutwater juice (first food today). No reaction

- 18:00:
- feeling slightly better
- sipped halph of my potassium water so far
- took more B1 and Mag Glycinate

- 19:00:
- I dont know what happened, but im feeling much better. Symptoms still there but something is different. Is it the "overdose" of B1 im loading up on since day 4? The Magnesium glycinate? The Potassium Chloride i started drinking today? The food starting to help now even though it didnt the last days? I dont know, but i keep going. Crying tears of joys but still scared

- skin burning/crawling/needling gone

- 21:00
- drank my potassium water since last timestamp, took Mag Glycinate, ashwahganda, NAC, Taurine, Aspirine, Cetrizine, iodine, multi-vitamin
- rushes of symptoms here and there, something is still different, still feeling better overall
- dizziness set in, can be from the glycinate/ashwagahnda
- ate around 300mg of my fruit/brocolli soup, no reactions


- 22:00:
- drove around city with my scooter, crying and screaming my lungs out for feeling like a human again during this time

- 23:30
- Melatonin, Taurine, NAC, L-Teahnine
- 50g of cooked salmon with skin
- 100g of brocooli/fruit soup (very slight and short lived reaction)
- happy i didnt have to take a benzo today. Feel ready to go to sleep. Will update tomorrow on a hourly basis. Still a little scared but hopeful now.


Day 7:10.12.2025
(08:00):
- woke up after just 6 hours but feeling somewhat refreshed
- nervous system has seemingly calmed down, dont feel like im on a overdose of drugs anymore
- still obviously beat down from the the last days though
- after sitting down at my desk, small rush of anxiety and increased heart rate (orthostatic intolerance). Slight panic for a second, but realized i have to expect this with everything thats going on. It calmed down very soon
- ate 200g of broccoli/fruit soup, no reaction

(08:45):
- slight rush of symptoms unfortunately. kind of dissapointed

(10:00):
- unfortunately, still reacting (but not badly). Took, Magnesium, ashwagahnda, B1, TUDCA, Taurine, Probiotics

(11:30):
- still reacting. Not badly, but its there. Trying to distract myself somehow
- ate another 200g of my broccoli/fruit/coconut soup
- starting to get symptoms of having the need to do deep breaths. Not hyperventilating, but just deep breaths all the time
- very hot all the time and sweating

(13:00):
- unfortunately still reacting. Rush of symptoms after drinking pure coconut water. Very dissapointed and feelings of stress and doom are coming back
- skin (face, hands, legs) started tingling/crawling again
- symptoms increasing from drinking coconut water

(21:00:)
- Pattern Recognition: for some reason, drinking water (in any form) beginning of the day sends me into these symptoms for hours on end, and somehow my body is able to slowly tolerate it more the more hours pass. This pattern has been true for the past 3 days and today
- since the last timestampe i have been trying to distract myself as much as possible
- light walks in the nature of 30-40minutes
- driving around my electric scooter
- small little workouts (bunch of push ups and pull ups)
- lots of breathing work, trying out different methods. They help me with not going insane or going into another mental breakdown (though i still had another one today), but they unfortunately do not seem to lift the symptoms itself or make me tolerate water more
- went to the cinema alone
- overall just enduring the symptoms and trying my best to make time pass (time passes very slowly)
- writing down anything, being very religious about all of my food/water/supplements/electrolytes/everything and tracking everything
- currently experiencing slight symptoms after drinking coconut water, but like the last days, it always gets better during the day.
- backing down on certain supplements as per yannicks direction and trying to keep it to a minimum
- still debating wether i should go back to hospital and beg them for help. Idea is to get data on things i cannot test myself (insulin, glucose, inflammation markers etc)
- Scared of tomorrow. I expect to suffer, i just hope i feel a tiny bit better, i ask for nothing more

(21:30):
- debating wether i should turn this into a small water fast. My problem is water, not food (i dont react to food). Water fasting has always healed everything for me, minor or major. Maybe this is what i need right now and this refeed is stressing my body too hard. Maybe i need to heal my body through water fasting, while drinking water and that will get me back on track

(Note for this day:)
- its not just hot flashes anymore, i am actually much hotter throughout the day after drinking water, any second **this was due to food, in hindsight** . Sweating alot (havent had any sweat since my Fasting Period)
- urine and stool output seems adequate and healthy



Day 8 (Turning Point)11.12.2025
(11:00):
- slept alot
- shortly after standing up, unfortunately hit with slight rush of symptoms. Symptoms are similar to water/food reactions, but distinct.
- Body is probably just under extreme stress from so much suffering. First 3 days symptoms were only due to refeeding, otherwise not there
- managing though

(11:30):
- Experiment: I will abstain from water for now and instead start out with dry raisins (70g). Little water content but high in sugar (and other good stuff)
- Lets see how my body reacts. Before i would always start my day with water (like most people) or my food would always be high in water content

(12:00):
- at my doctors now, symptoms are setting in. Hot, tingling, increased heart rate and my body doing deep breaths on its own
- Blood Glucose measured at 132 (normal amount for what i ate)
- Temperature: 36.6
- Blood Pressure: 120/82

(12:30):
- got a hold of Benfothiamine at a pharmacy

(13:00):
- body is calming down from the first rush of symptoms from eating dry raisins
- Pattern recognition after this experiment: Looking at all reactions to water (and now to dry raisins), the deep breaths, the heat, Titans remarks about CO2 and metabolism, this MIGHT be a energetic/metabolic crisis
- Yannick has mentioned a energetic crisis
- This rush of symptoms came from raisins this time. This rush of symptoms had lasted for 8 hours yesterday, even longer the days before and today for just an hour and a half

(14:45):
- Test to confirm this pattern/theory:
- If we assume todays rush of symptoms/crisis has calmed down a bit already, i should be able to drink water/eat soup now without getting much stronger reactions
- This pattern has been true for the past days when the day was nearing its end.
- Drank/ate 200g of my fruit soup
- Took 150mg Benfothiamine, Multi-Vitamin with minerals important for B1-Therapy and the paraxodical reactions to it
- Took TUDCA, Magnesium Glycinate, ignoring other supps as per Yannicks direction
- going for a 40-minute walk now

(15:45):
- back home, its cold outside but im feeling warm and good
- was extremely cold during my 7WF + 7DF. So very distinct to how im feeling now
- NO INCREASED (OR SMALL) REACTION TO FRUIT SOUP AFTER FIRST RUSH OF SYMPTOMS(EXPERIMENT)
- Symptoms of extreme stress still there of course (dizziness, tingling skin, slight anxiety, auditory/visual sensitivity)

(16:15):
- ate another 100g of my fruit soup, lets see what happens

(16:45):
- no reaction to fruit soup
- ate 200g of watermelon (lots of water), 100g of dry raisins, 100g of fruit soup

(17:15):
- no reaction to last food/water so far
- todays episode/crisis has indeed ended very soon today
- expecting this pattern to continue over the next days until it has stopped completely
- Wondering if the B1 is helping me with this. Something is telling me it does

(18:00):
- drinking coconut water, eating banana, taking more supps
- i have clearly entered todays state of... not being in agony anymore much much sooner than yesterday
- considering how late i woke up and how soon i already feel great, the window of crisis has dropped drastically since i started actively treating my situation

(18:40):
- slight reaction to larger intake of coconut water
- HAVE TO PACE MYSELF AND GO SLOW, EVEN IF I FEEL GOOD

(21:00):
- drank coconut water, ate bananas, took more of the supps since last timestamp
- no reactions if i sip/eat slowly
- obviously still having symptoms from the extreme stress
- Yesterday i said all i was asking for is to simply feel a little bit better tomorrow, and i do
+ 4kg (10lbs?) since my refeed
- NOT SCARED OF TOMORROW
- READY TO TAKE ON TOMORROW WITH CONFIDENCE




Day 9 (Day of Redemption)12.12.2025

(08:00):
- Woke up with no dizziness, no skin burning/crawling/anxiety

(08:40):
- at doctors
- fasting blood glucose: 94mg/dl
- Temperature: 36,7 C

(10:450):
- ate 150-200g of dried raisins and a banana for next test until shortly before my next doctors visit again (trying to test my insulin response here)

(11:15):
- VERY SLIGHT RUSH OF SYMPTOMS
- getting hotter, body doing forceful deep breaths again
- no DIZZINESS, NO SKIN CRAWLING/BURNING, NOT HOT FLASHES

(12:00):
- at doctors again
- Blood glucose: 149mg/dl (not bad for coming out of such a extended fast i guess)
- temperature: 36,9 C

(12:15):
- Blood work from day 6 arrived
- Overall: Very good results (despite day 6 being a really bad day). Certain Markers indicating dehydration were elevated/reduced, but that was to be expected
- Natrium at 138 mmol/l on day 6(3 days ago). Should really start upping my salt intake now
- Free T3: 2.25 ng/l (2.04-4.4 ref range)
- TSH: 1.30 uU/ml (0.38 - 5.33)
- tested positive again on borrelia burgdorferefi (this time tested on certain proteins)
- negative results on Epstein Barr Virus
- Protein Markers (like Albumin) and Inflammation markers speak against Herxheimer-Reaction, even though those are not definitive ways to test for Herx-Reaction

(13:00):
- basically no reaction anymore to food and water (since i last ate). Sipped some coconutwater, no reaction.
- Very slight dizziness from the raisins and the coconut water, nothing more
- Feelings of stress and exhausting from the last days still there, but those stupid reactions to water are truly healing now

(18:00):
- since last timestamp almost symptom free
- slowly developed very small rush of symptoms after eating/drinking too much
- Starting to realize: Food and water symptoms seem to overlap a bit, but it still seems to cause 2 different reactions in my body
- Water causes dizziness (wobbly kind of dizziness), food doesnt.
- Water causes hot flashes, while food causes me to be generally hot all the time
- Water creates a weird kind of head pressure around my scalp, food doesnt
- Water creates changed vision and auditory sensitivity
- Water was the one giving me crippling levels of anxiety, which was probably the one symptom that really took the last toll on me and made me break down mentally (was enduring the other symptoms from water much better before this set in)
- Food gives me forceful deep breathing, but not water
- Food increases heart rate for extended periods in "normal amounts", water increases heart rate drastically in what feels like a mini panic attack
- Overall:
Food:
- While symptoms from food are intense, they are much more pleasent and really do feel like my metabolism and energy production is simply increasing.
- Food symptoms seem like natural and normal bodily reactions
- Food symptoms didnt set in until after the 4th-5th day for some reason
Water:
- Symptoms from Water are unnatural, weird, unpleasent, crippling and seem much more tied to my nervous system being in a state of extreme stress
- Water symptoms were there even on the first day, and began becoming much more severe and chronic the following days
- Anyways: GOTTA SLOW DOWN

(22:00):
- water symptoms have calmed down since reducing my water intake
- Reactions to food are pleasent and healthy, feel warm and energetic
- still keeping up my supplement game

(23:30):
- "wobbly" kind of dizziness is persisting for some reason. Feels like my head is tipping over constantly, as if you would try to stand up on a surf board
- trying to grab something thats infront of me is a challenge
- will have to do some experiements with water/salt tomorrow to check where its coming from
- not suffering from it, but very annoying





Day 10 (set-back)13.12.2025
(11:00):
- Unfortunately woke up with feelings of stress, anxiety, skin crawling, dizziness
- recognize this state from one of the other mornings
- didnt sleep well, dont feel refreshed at all
- I did eat/drink too much yesterday evening, perhaps it overloaded my nervous system
- Second time i have something that is just there and not as a reaction to food/water. I dont like this
- dissapointed as i expected to feel almost normal today, but trying to stay positive.
- Deep sense of anxiety/nervousness that i can feel in my chest is the most annoying one, its like a direct antidote to my willpower/mental strength
- Perhaps the benfotiamine is doing its paradoxical reaction? I dont know

(11:45):
- ate 100ml of low fat kefir/honey and a banana, 300mg Magnesium.

(12:30):
- small rush of deep breaths and heat (for maybe 20 minutes), no water symptoms though

(12:45):
- did Buteyko Breathing, it actually did help me calm down. It didnt diminish my symptoms from this morning, but it made mefeel better
- Perhaps symptoms from this morning really are just a stressed nervous system from eating too much yesterday and having bad sleep. Never had symptoms of stress (or stress itself really) in my life so the whole "its just stress" meme is new/unknown to me
- trying to figure out if it was too much fat/protein yesterday (ate 200g of salmon). Taking TUDCA for liver health but perhaps its just too much for my liver to process

(13:15):
- ate some 100ml kefir/honey
- deep breaths increasing a little bit

(13:45):
- Overall symptoms are increasing abit as im eating sips of my honey/kefir
- deep breaths returning
- Note to myself: Have to give myself some more time (in the morning) before i can safely assume "no reactions" to food/water
- Weirdly: Reactions to much larger/faster intake of energy/sugar yesterday morning was much shorter lived
- Still going to take things slower today though

(15:00):
- body and symptoms of "stress" have calmed down noticeably
- Reactions to food/water are still mild or non-existant. Atleast this pattern has reduced substantially
- As explained yesterday, i feel like i really know whats going on with my body when it comes to food/water
- But "Stress" symptoms with no known cause/trigger is still a mystery, maybe ill figure that out too the following days

(16:00):
- symptoms from food are there when eating something sugary. Doing Buteyko when i notice the deep breaths.
- Head Pressure around my scalp has come back
- Sidenote: Big shifts of electrolytes from increased sugary foods might be causing symptoms, as i have been eating way more food/carbs/fruits/calories the last days since tolerance to food/water has improved
- Needs for potassium have probably increased substantially. Will supplement extra potassium chloride (2g, 1g pure potassium) to my coconut water

(16:15):
- drank a bit of my coconut/potassium water and unfortunately got a rush of symptoms
- Dizziness, anxiety, hot flashes BUT ALSO DEEP BREATHS (from water)
- Cant be the potassium itself as the reaction happened too fast
- Note: this reaction is distinct to the symptoms of "stress" i woke up with, today
- Overall feeling pretty hot/warm though
- dissapointed i got another reaction from water, thought this shit is over

(16:30):
- Symptoms increasing, fuck....

(16:45):
- Buteyko breathing helped a little
- symptoms are reminiscent of how i felt a couple days ago when things were bad
- not as crippling but big setback from yesterday
- trying to tell myself its the Benfotiamine

(17:00):
- wobbly kind of dizziness from water is back
- drinking plain water gives me rush of symptoms
- Im ready to tolerate and accept other symptoms, but the reactions from water i do not. I do not want to accept that im getting dizzy and anxious and hot flashes from water. I cannot be reactive to water, that is just stupid
- trying calm myself down and not take this as a bad sign

(17:30):
- symptoms calmed down abit
- kept drinking a little bit more water just to "challenge" it, didnt get much worse after first onset of reaction
- head pressure in the back of my scalp + wobbly dizziness still there, trying to understand where they are coming from
- Wobbly dizziness from water ( i think it comes from water) is different to "stress" dizziness i woke up with today

(18:10):
- most symptoms have calmed down substantially
- wobbly dizziness persists
- Note: Even though i have just talked about potassium with Titan, i feel like i might actually be taking in too much potassium. Todays reactions came from drinking coconut water with potassium chloride. I cannot tell if it was just the water, or the high potassium might have played a role.
- Reasoning: Only once in one of my water fasts (june 2025) was i drinking too much potassium and i was reacting to it. I wasnt aware it was the potassium, until i went to the ER and i had high potassium. Ive thought about it, and i could swear the symptoms from it were similar to what i got today. Big correlation: I got deep breaths from todays coconut water (first time as a reaction to water), which is also what happened to me during this water fast with too high potassium
- This is just a theory, i might just be reacting to water and it has nothing to do with potassium.
- Really unsure about salt at this moment. Currently taking in just 1g of salt per day. Sodium was at 138 (ref range: 135-145) 4 days ago.
- Salt is a delicate factor after a dry fast and "salt behaviour" in the body changes drastically.
- Maybe i should trust the blood test and increase my salt tomorrow. No workaround but to just try it out.
- Happy the symptoms have calmed down a good bit and somewhat early. Day was still stressfull

(19:50):
- was outside doing things, felt good at first, but started getting some nervousness while walking around
- came home, ate some cooked rice and got a rush of symptoms for a short period of time (sigh)
- anxiety and skin crawling are back

(21:00):
- increased body temperature from the food
- Temperature: 37 C°

(22:10):
- body has calmed down alot, still lingering symptoms here and there but managing
- ate a big meal of watery rice/raisins/pineapple, feeling good

(22:30):
- REALLY thankful that atleast my nights/evenings are spared from agony and that im able to sleep.
- Couldnt imagine tolerating this horror at night

(00:20):
- drank some good amount of water and coconut water. Barely noticeable symptoms.
- WHY THE FUCK DO SYMPTOMS DECREASE BY SUCH A BIG AMOUNT OVER TIME/OVER THE DAY? WHY THE FUCK DO THEY COME BACK IN THE MORNING? (sigh)

(01:00):
- noticed in the shower my skin is reacting to warm water. It gets tingly and itchy. Remindes me of the hives that covered 30% of my body during the bad days of Lyme disease (i dont like this)
- overall have a feeling theres some overlapping with some of my lyme symptoms i had last year. Out of the 30 symptoms i had, there were 2 or 3 that kind of overlap with what im going through right now. Perhaps not a big surprise considering my lyme history plays a role and nervous system overreaction can look the same for different triggers.
- Overall much different experience compared to lyme symptoms though
- Going to bed now. A big Fuck You for tomorrow morning






Day 11 (step-forward)14.12.2025
(10:30):
- slept well

(11:30):
- so far, no symptoms or very very slight ones
- only slight anxiety in the chest
- Big Fuck You from yesterday seems to be working.
- Maybe i need a higher dose of Fuck You Tomorrow Morning before going to bed

(12:00):
- decided to "challenge" the reactions and eat/drink more than i usually would in the morning
- around 200ml of water, 100ml of kefir + honey, 2 bananas (yes thats alot for me)
- took my vitamin B stack, multi-vit and 300mg Magnesium Glycinate

(12:30):
- symptoms set in, but in relation very weak
- wobbly dizziness set in (very annoying)
- decided to go for a walk

(13:40):
- 40 minute walk, felt very good
- head pressure, wobbly dizziness and slight headaches are there. Seems to be a unique reaction to water from what i can tell
- wobbly dizziness and head pressure from water always there, even in the evening when i wasnt reacting to water anymore
- trying to understand why water is doing this. It kind of feels like my salt/aldosterone system is still out of whack and my brain is pulling too much water
- ate some 200ml of more kefir + honey

(14:10):
- so far, symptoms under control, actually decreasing since my first meal.
- no increase from kefir
- being cautious though, i learned from yesterday that symptoms can be delayed

(14:30):
- Realized today that while im trying to take all Benfotiamine Dependencies, i missed out on a crucial Magnesium dependency
- B1 -> Magnesium -> Vitamin D. So taking Vit D from now on. Starting at 2500 UI per day.

(15:00):
- Big meal: ate 400g of watery rice/carrot soup and 100ml of kefir, lets see how i react

(16:00):
- Very very slight rush of anxiety in the chest
- So far no reaction, feeling great. Wobbly Dizziness reduced
- Telling myself the Benfotiamine is helping and my supplement stack is getting on point
- another 400g of watery rice/carrot soup and 100ml of kefir
- 100ml of coconut water

(17:00):
- wobbly dizziness, but otherwise no reactions really
- feel like increasing my salt intake has helped alot. Currently taking in around 2-3g per day through food

(20:30):
- Wobbly dizzines subsided since i last ate
- ate a bunch of watermelon very hastily, ingesting way too much water, completely forgot about my symptoms for a second
- Very small reaction 5 minutes later
- Head pressure, slight headache and wobbly diziness are back though

(00:30):
- Ate alot, no reactions
- drank alot = NO WOBBLY DIZZINESS
- Today was a good day
- Obligatory Big Fuck You for tomorrow morning
- First time i feel completely symptom free i think





Day 12 (15.12.2025)
(10:30):
- woke up feeling somewhat groggy but overall fine

(11:30):
- so far no symptoms
- ate 200g of rice soup, 100ml of kefir, 200ml of coconut water
- Took 400% of B-Complex, 150mg Benfotiamin, 300mg Magnesium Glycinate, Multivitamin/Minerals, Probiotics, 2500IU Vitamin D

(12:30):
- very very small reactions an hour later, slight wobbly dizziness, slight heat
- slight headpressure and headache

(15:15):
- only lingering symptoms left since my last meal. Doing groceries now, going to start adding more protein and fats to my diet

(21:10):
- eating large meals and drinking larger amounts of water/coconut water has either no reactions or just very very short lived ones.
- Have a good feeling its finally over
- Will do a final assesment in the following days, trying to make sense of the whole situation
- Going to bed now






Day 13 (16.12.2025)
- Note for Day 13.
- Forgot to take my magnesium for just 8 hours
- started getting some intense symptoms of stress, muscle weakness (could barely walk), extreme brainfog (couldnt form a single thought), fatigue, irritation, anxiety, drowsiness. Overall very unpleasent
- Was confused as these symptoms were overlapping, but still quite distinct to what i was experiencing until now
- Rembered i forgot to take my Magnesium for this day.
- Took 320mg, after 40 minutes, all symptoms subsided. Rush of extreme calmness rushed through my body. Literal feeling of my nervous system calming down substantially

- Demand for Magnesium has reached extreme levels due to this B1 protocol. Have never experienced symptoms of low magnesium to such an extent in such a short amount of time





Day 14 (17.12.2025)
- Notes for day 14:
- Feel pretty hot all day long. Not the burning/hot flashes as reactions to food/water, but just pretty hot
- No symptoms but weird kind of brainfog creeping up on me, very annoying
- Started eating much more since the last 3 days so its probably due to that





Day 15 (18.12.2025)
Notes for day 15:
- had stool like 7 times today already. Not diarrhea, but just alot of soft stool. Stool wasnt soft at all the days before
- might have reached magnesium saturation? Was taking 700-900mg of it since day 3-4 i think
- Reactions to food/water are zero
- brainfog, drowsiness from yesterday still there and much stronger
- hard to think. "Clumsy" kind of dizziness (yes, yet another different kind of dizziness) set in
- Head pressure and headache (never had headache the first 12 days, only started appearing the last couple days)
- These symptoms are distinct in their patterns from what i was experiencing before
- Nauseous too
- started researching intensely, trying to figure out whats wrong
- came up with salt intake perhaps being the problem
- realized i wasnt paying attention to salt intake the last 2 days
- started drinking coconut water. Mixed 1.6g of salt and 400mg of potassium into 1 liter. Drank half of it over 2 hours
- symptoms started going away. Only clumsiness and head pressure left (a bit). Brain fog and other symptoms heavily lifted
- started peeing an ungodly amount after coconut/salt drink
- symptoms and reponse to salt intake, match symptoms of low serum sodium perfectly (based on my research)
- My body/brain/kidneys are still heavily confused and havent come out of the dehydration adaption yet. Electrolyte balances are completely out of whack and response to various amounts of electrolytes is chaotic and very sensitive
- scared my sodium went too low in the last days and today. Symptoms of hyponatremia werent severe (didnt throw up or went into paralysis), but potentially medium (based on research)
- correction of low sodium states is very very delicate
- the lower the starting serum sodium that needs to be correct, the higher the chance for Osmotic Demyelination Syndrome
- very scared of Osmotic Demyelination Syndrome. Feelings of improvement mean nothing unfortunately. ODS can set in days after salt was corrected too fast
- debating wether i should go to the hospital to get my sodium checked. If its low, i know im in risk and should stay in the hospital. Do not trust myself to correct sodium by exactly 5-8mmol/l per 24 hours just through self-medicated salt intake

- a couple hours later when i felt much better, couldnt believe it but actually got a short lived reaction from a little bit of water again. My system and my automatic regulatory mechanisms are completely fucked it seems

- Ate a ridicilious amount of food yesterday. Pretty sure this triggered my system to become chaotic again
- Increase in Food/sugar probably caused greater shifts of electrolytes into the cells/out of the blood, giving me reactive hyponatremia
- Osmotic gradient from the dry fast is probably still there. Osmolytes in my brain/body are probably still high. Both result in a adaption to serum sodium levels that are very sensitive to even slight drops
- Bodily adaptions/functions are still in this dehydrated state i assume.
- The strong reaction to having missed magnesium dose for just 8 hours might speak for this theory too
- After some further extensive research on ODS, chances of this happening to me are slim, despite the moderate severity of my low-salt symptoms
- Have to control myself with food until my body has learned to deal with shifting electrolytes better




Day 19 (21.12.2025)
- The last couple of days have shown that my body hasnt fully adjusted yet
- Overall i feel much much better and i can go through my day without much issue
- Weird things still happen though, mainly due to electrolytes.
- started to react to too much electrolytes i think. Sometimes i'd be drinking my potassium/salt water (800mg/3g/1.5 liters) and i would start getting muscle weakness, increased breathing, head pressure etc.
- I thought it cant be due to the electrolytes. But when i started drinking plain water, it would go away and i would start peeing like 1 liter in just 1 hour (this is my body/kidneys way of balancing out electrolytes). Maybe im saturated? I dont know, and i cant tell which of the electrolytes it is. I assume potassium
- drinking around 800mg - 1g of potassium extra, together with all my potassium rich foods. Perhaps i should stop as my body is finally getting the nourishment it needs from food alone
- Today ate 2 bananas and drank 1 liter of milk slowly over 4 hours, started getting slight muscle weakness, head pressure, headache. Lifted when i stopped
- muscle weakness points to the fact its an electrolyte issue, and not my nervous system. Muscle weakness was never a part of my nervous system reactions to food/water.
- Body is still doing weird things and adaption to dehydration/malnourishment isnt fully recovered.
- Like i shouldnt suffer from hyponatremia symptoms after eating little salt for just 2 days. And i shouldnt be getting symptoms of high potassium just because theres potassium in milk
- based on research, might have reset osmostat syndrome in reverse (for hyper-instead of hyponatremia)
- osmolytes in my brain are probably still there, as the "wobbly" dizziness still happens sometimes (brain is pulling too much water)
- Anti Diuretic Hormone and vasopressin secretion is still chaotic (peeing 1 liter in 1 hour, or barely peeing at all, or peeing reguarly)
- bodily reactions to water/electrolytes(salt) are healthy though (peeing when i should, not peeing when i shouldnt). Baseline is just still stuck in dehydration mode. Jumps in electrolytes and blood osmolality (like drinking water in the beginning) were met with strong reactions from my body, causing big shifts in blood pressure and blood osmolality, perhaps causing my nervous system to react this badly and giving me the crippling symptoms
- Proof my RAAS system is working: After correcting the reactive hyponatremia on day 15 with potassium and salt, started peeing a shit ton -> correct reaction from my body
- Nervous System Reactions to food/water are basically gone though. Currently just experiencing non-nervous system symptoms because my body is trying to adjust with varying levels of electrolytes, which it has problems with currently.
- sodium was 140 at day 4. This is after 4 days of very little salt and lots of water. My osmostat syndrome was fine-tuned for a much higher sodium level probably, which is why missing out on salt for just 2 days (day 13-15 i think) would give medium-strong symptoms of hyponatremia (low serum sodium)
- sigh.... have to wait this out i guess. Thinking about doing a short water fast to get my nervous system back to baseline. If things dont improve for another 2 weeks, i might consider it. Will probably not need it though
- Happy i created this journal to document my symptoms. When i look at everything, many things seem to overlap and be the same reactions to the same things, but typing everything out helped me to make the distinctions between all of them, as i realize they are definetely different reactions due to different bodily systems
- as per titans last video, might have to reduce my magnesium from 900mg to 750mg. Stool is soft and plenty. ca. 2 weeks of 900mg magnesium loading might be enough if i remember correctly. need to watch the video again

- thinking about how much worse this could have been if i wasnt as "autistic" about biology, medicine and research (or didnt research dry fasting for 6 months before i actually did it). So many variables, so many symptoms, so many different things going on with my body. Just figuring out i had reactive hyponatremia from day 13-15 was not easy. Could have easily missed that, attribute it to something else or think it was just another chaotic response from my nervous system. Doctors absolutely useless. Could have landed in the ER, they look at my sodium and think everything is okay.
I hope this never happens to anyone else






Day 24 (26.12.2025)
- Unfortunately had 2 very bad days the last 2 days (24.12 and 25.12)
- Symptoms were different to food/water reactions, but overlapping
- Symptoms were not in reaction to food/water. Drinking/eating didnt make it worse or better.
- Supplements/electrolytes didnt make it worse or better
- Symptoms just appeared in the morning and got progessively worse over the day
- Always symptom-free after 18:00 - 20:00
- Honestly dont have any opinion on the last 2 days. There was no pattern, no response to anything, no reaction, no behaviour. They were just there for no reason
- This is not good
- Scared i sent myself into chronic dysautonomia after this whole ordeal
- might have a couple theories as to what i did wrong to trigger this but its just guessing currently
- Today was a good day, feel much better. But unfortunately doesnt mean much by now
- Ate like 3500 calories of unhealthy christmas food (entire cake and so on)






Day 25 (27.12.2025)
- Not a good day today
- Somehow reacting to water/food or maybe not. Its so delayed that i cant tell if its coming from that. Reactions are coming 30-60 minutes after drinking/eating
- Reactions to it are different though. Symptoms im currently handling do not match food/water reactions that i was experiencing previously
- Overall im confused and kind of lost. Symptoms have changed and as said yesterday, there seems to be no pattern or behaviour
- Plan for the next 2-3 days is to start from zero when it comes to supplements and add them back one by one. Perhaps im overloading on something without noticing. Walking in the dark here but i just have to keep trial-error
- Dialing down on the amount of food im eating. Have been overdoing it alot the last days (like eating an entire cake in 1 hour). Today i will eat healthy and normal again





Day 26 (28.12.2025)
- Feel much better today probably because i was eating healthy yesterday
- Did react to food/water a little in the same way how i felt yesterday
- So new symptoms do seem to come from food/water, they just changed and arent as instant anymore as they used to be
- The fact that i feel better today tells me it was in response to me giving my body a break yesterday.
- At first i didnt think this was happening from me eating too much, because when i did feel good and symptom-free, i wouldnt get any reactions from food/water
- This is my theory: When i am symptom-free (when my nervous system is calm), eating too much wont send me into chaos right away. It takes atleast a day or two before my body starts getting chaotic again. Once my body is chaotic again, its when i start over reacting to even little food/water and it takes time for this flare to calm down. The last 7 days have been true to this trend quite clearly. I dont flare instantly anymore. I just start flaring after a couple days of bad food choices and this flare just takes time to calm down
- Have forgotten to mention that i was eating alot of unhealthy christmas food since 22.12
- My remarks the last days about symptoms not being in reaction to food/water are not really true. They are just so delayed that it makes me think that is the case.
- The fact that giving my body a break yesterday made me feel much better today is proof to that.
- 2 days ago (26.12), i was eating a enourmous amount of food. Like 3500 calories and maybe more. So, i was flaring yesterday (27.12) for seemingly no reason and despite eating healthy.
- This confused me. On a day where i eat too much, i feel okay. On a day i eat healthy, i flare for no reason. Its all just delayed and once it sets in, my body just flares, wether i eat or not.

- Will watch and see if this pattern holds true for the next day.





Day 27 (29.12.2025)
- Fortunately and as expected, still feeling much better today as i was eating healthy and carefully yesterday
- (New) symptoms from food/water are much less than yesterday, barely noticeable
- Have to give my body more time to adjust
- Overall the progression of my condition is like this: Instant strong reactions from food/water the first 3 weeks. Food/water would send my body into stress and chaos immediately. Now: Eating badly for a couple days is okay, stress accumulates until it is too much and my body goes into a flare once again.
- Fasting in the night/during sleep was enough to "reset" my nervous system back into a flare. Now it takes severeal days of eating badly to go back into this state
- Electrolyte issues do not seem to be there anymore. Able to tolerate electrolyte fluctuations without much issue it seems







Day 32 (03.01.2026)
- Theory has stayed true since last update. I ate healthy and small portions since last update and my symptoms got weaker and weaker each day.
- Today i felt almost completely symptom free
- As a test, eating bigger (but healthy) meals for today/tomorrow and see what happens.
- ate alot of healthy food late in the evening
- Insomnia at night, couldnt sleep for 2-3 hours





Day 33 (04.01.2026)
- For test purposes, ate alot of unhealthy food today
- 4 hours later, head pressure and weird body sensation
- EXTREME insomnia. Couldnt fall asleep for 5+ hours. Felt weird, inflamed, unwell





Day 34 (05.01.2026)
- Test results: Typical symptoms from food havent come back the last 2 days, but i am very obviously reacting to unhealthy and large amounts of food. When i eat healthy, i feel good. When i eat unhealthy, i feel very bad. My experiment the last 2 days has proven that. This experiment has also shown my body is tolerating more. I didnt get send into days of agony again and was able to bounce back today quite quickly
- Going to keep eating healthy
- Probably, truly getting out of the woods now





Points about the refeed:
- Around 0.2 - 0.4g of salt per day for days 1-3 (through food)
- mostly cooked fruit and coconut water since day 4
- Bhought/took supplements and started "treating" this crisis from day 4
- Everything very low fat
- All portion sizes were generally very small.
- Apart from the First Meal on Day 3 (when things got bad), everything was eaten/chewed/drunken very slowly.
- 2.8kg gained in first 3 days
- ca. 2 liter of water first 3 days (cumulative effect leading to my body being sensitive?)
- Overall i was very careful about my refeed




My Mistakes:
- Vaped nicotine around 3 times per day (three puffs in total per day) as i was not willing to go through a withdrawal throughout the experience
- Went from a 7 day Water fast into this 7 day Dry Fast

Some points about me:

- 30 years old
- Very fit and athletic
- Completely healthy for entire life, no history of any illness
- developed lyme disease 1 year ago (westernblot positive), developed MCAS, POTS, CFS through lyme
- Healed all (except the bacteria itself of course) through water fasting. Symptom free since april this year, directly after my extended water fast.
- Lived life normally since april, again absolutely no symptoms
- No history of any mental problems
- Very experienced Water Faster, like 3+ weeks of Water fasting = no problem (never had complications, ever)
- three, 3 day Dry fast under my belt before 7 day DF, no complications


Patterns/Notes/thoughts:
- Any type and amount of water gives me the same pattern of symptoms
- bloodwork is healthy on day 4 (hospital) based on bloodwork
- potassium 3.7 at day 4 (low in ref-range
- Symptoms usually start 5-15 minutes after intake
- One time, the symptoms set in 2 minutes after a tiny bite of soup
- Nervous System Hell Hole potentially coming from extreme herxheimer reaction, causing MCAS symptoms?
- Cetrizine has no effect on symptoms like it used when i had MCAS (maybe not allergic?)
- Very low CRP on blood test speaks against herxheimer?
- Drinking water jump starts symptoms for entire day. Keeping drinking water slowly for the day doesnt increase symptoms too much. First 3 days had 2 liters of water, following days much less. Reactive shock to water intake that build up over first 3 days, leading to this sensivity now?


What is happening to me?
Have i just broken my immune and my nervous system due to the "shock" of fasting?
How is it possible to react to 2 sips of water this badly?
I am scared to keep living like this. To be "allergic" to water

Im having an unusually difficult time right now. Im basically unable to drink anything right now and even watery food triggers these symptoms. One bit of my soup and im reacting more and more. Basically just enduring the situation right now.

I do not expect you to know whats up. Nothing of whats going on makes sense and nothing similar online can be found. Im usually very good at finding out whats wrong with me.
This scares me though, im lost at what im supposed to do now.

Any opinion is appreciated. I will go the hospital again when things go bad. Will probably need to go to my doctor just to hydrate through an IV. But i know they cannot help me.

My Blood tests from the hospital visit:

Re: In dire need of Help: Strong reactions to water/food during refeed

Post by Titan »

First thing that pops into my mind is thiamine (vit B1) deficiency, which can lead to vagal nerve dysfunction.
I think the rapid onset of symptoms (2minutes after sipping tiny amounts of water) would speak for that.
Buteyko breathing, humming/singing, gentle stomach massage (like block therapy or with a soft massage ball) might help down regulate the vagus.

Please go the ER sooner rather than later, and let them know you suspect thiamine deficiency.
Prolonged stress, infections, illness or caloric reduction can deplete thiamine.
They are used to repleting alcoholics, and have protocols to do it safely.
Blood tests for thiamine can give false positives, unless severely deficient.
It does not replete with food alone. It must be supplemented, often needs cofactors or injection to properly replete.
Elliot Overton has great information about it.

This is just my shot in the dark, and it could be something entirely different. Am curious what Yannick might have to say.

Here is ChatGPT's opinion:


Analysis of Potential Conditions Following Extended Dry Fast and Refeeding

It is critical to preface this analysis with a strong medical disclaimer: I am an AI and cannot provide medical advice, diagnoses, or treatment recommendations. The information provided here is for informational purposes only, based on the symptoms you've described and general medical knowledge. Given the severity and unusual nature of your symptoms, it is absolutely imperative that you seek immediate and comprehensive medical evaluation from qualified healthcare professionals. Your detailed account is extremely valuable and should be shared fully with any medical practitioner you consult.

Your experience describes a highly complex and distressing physiological reaction, particularly concerning after an extended dry fast and during refeeding. The rapid onset of severe symptoms like extreme dizziness, nausea, hot flashes, heart racing, strong anxiety, difficulty thinking and talking, and head pressure, triggered by even small amounts of water or watery food, points towards a significant systemic dysregulation. The fact that your initial CT scan and blood tests were reported as "good" is important, but it doesn't rule out functional issues or more subtle imbalances that might not be immediately apparent in standard emergency panel tests.
Potential Medical Conditions and Syndromes:

1. Refeeding Syndrome: This is a serious and potentially life-threatening condition that can occur when nutrition is reintroduced too quickly after a period of starvation or significant undernutrition. While your blood tests were initially good, refeeding syndrome involves rapid and potentially fatal shifts in fluids and electrolytes, particularly phosphorus, potassium, and magnesium. These shifts can cause a sudden change in metabolism, leading to a variety of symptoms including fatigue, weakness, confusion, difficulty breathing, heart palpitations, increased heart rate, low blood pressure, nausea, vomiting, and even seizures. The symptoms often begin within 72 hours of refeeding, but can also manifest later, and can progress rapidly. Your description of symptoms like heart racing, dizziness, and nausea aligns with common manifestations of refeeding syndrome. Even if initial blood tests appear normal, significant shifts can occur as the body tries to process nutrients, placing enormous demands on depleted stores of intracellular ions. Refeeding syndrome can affect anyone who is unable to consume or absorb calories due to a medical condition, life circumstances, or purposeful fasting. The symptoms are nonspecific, and there is no formal diagnosis. It is treated by carefully adding fluids, vitamins, minerals, and calories to the diet or through an intravenous (IV) line. Refeeding syndrome may start within a few days after nutrition is reintroduced after fasting or malnutrition. It's usually described as occurring after a "prolonged" time of not taking in any nourishment. No single agreed-upon definition of timing exists when refeeding syndrome may start.
The clinical symptoms associated with refeeding syndrome are highly varied, reflecting electrolyte changes and compromises in biochemical changes as cell membrane potentials and cellular functions. Patients may present with multisystem complaints ranging from nausea to hypotension. It has been observed that a patient's first described feeling of nausea can be interpreted as a precursor to hypotension.
A sudden change in the balance of phosphorous and other electrolytes causes the heart to work harder to manage a higher blood volume, which can cause symptoms such as fatigue, weakness, confusion, difficulty breathing, nausea & vomiting, and heart failure.

2. Electrolyte Imbalance and Dehydration/Fluid Dysregulation: Even if your initial hospital blood tests were "good," the dynamic nature of refeeding after a severe dry fast means electrolyte levels can fluctuate rapidly. Prolonged dry fasting can lead to significant dehydration and electrolyte imbalances, which can become life-threatening. Symptoms such as headaches, fatigue, irregular heartbeat, muscle cramps, and nausea are commonly associated with electrolyte deficiencies. Your body's ability to regulate fluid balance and electrolytes can be severely disrupted, causing adverse reactions even to small amounts of water. The shift from a dehydrated state to reintroducing fluids can overwhelm the system, potentially leading to symptoms of both dehydration and paradoxical fluid overload at a cellular level. When essential electrolytes are lost, it can lead to significant imbalances in the body, with common symptoms including fatigue, confusion, irritability, nausea, vomiting, headache, and an irregular or fast heart rate.
During dry, wet, and intermittent fasting, electrolytes are depleted. When potassium levels drop and sodium levels rise, it could result in high blood pressure.
Prolonged dry fasting can cause dehydration, which may result in electrolyte imbalances and low blood pressure, potentially being life-threatening.

3. Autonomic Nervous System (ANS) Dysfunction/POTS Exacerbation: You have a history of POTS, which you claim to have healed. However, the symptoms you describe – extreme dizziness (though it improves upon standing, which is atypical for classic orthostatic hypotension, but still points to a challenge in blood pressure regulation), heart racing, hot flashes, and anxiety – are highly suggestive of an autonomic nervous system dysregulation. Fasting, especially prolonged and extreme, can significantly impact the ANS. In individuals with POTS, symptoms are often exacerbated after meals, with postprandial tachycardia being a common observation. The rapid onset of symptoms after intake, including heart racing and dizziness, strongly aligns with such a response. The body's "fight or flight" (sympathetic) response can become overactive, leading to the anxiety and rapid heart rate you're experiencing. POTS is characterized by an abnormally large increase in heart rate upon sitting up or standing, accompanied by symptoms such as lightheadedness, brain fog, weakness, fatigue, headaches, heart palpitations, and nausea.
Some patients with POTS report worsening of symptoms after meal intake, including mental clouding, blurred vision, rapid heartbeat, and lightheadedness.
Fasting can influence the autonomic nervous system, and while it can activate the parasympathetic (rest and digest) system and lower the stress response in some, it can also lead to symptoms like increased pulse rate and orthostatic hypotension in others.

4. Mast Cell Activation Syndrome (MCAS) Flare: Your history of MCAS is highly relevant. MCAS involves mast cells inappropriately releasing inflammatory mediators, leading to a wide range of severe symptoms affecting multiple body systems. Extreme reactions to seemingly innocuous triggers (like water or small amounts of food), hot flashes, and anxiety are classic presentations of an MCAS flare. Fasting itself can be a stressor for mast cell patients, and reintroducing foods can trigger a significant inflammatory response, especially if the body is highly sensitized. While some people with MCAS find intermittent fasting beneficial, prolonged or extreme fasting can also trigger flares. MCAS causes repeated episodes of severe symptoms in multiple areas of the body, which may include low blood pressure, flushing (hot, red or pink skin), itching, hives, nasal congestion, swelling, constipation or diarrhea, abdominal pain, vomiting, shortness of breath, weakness, or fainting.
Fasting most certainly puts the body into a state of stress, and in some mast cell patients, stress can trigger a flare of symptoms.
Research has shown that fasting reduces mast cell degranulation and histamine release, but it's important to work with a healthcare practitioner if considering dietary changes like intermittent fasting, especially with conditions like MCAS.

5. Herxheimer Reaction (Lyme Disease): You specifically mentioned considering an "Extreme Herxheimer reaction from borrelia." While you noted your symptoms don't perfectly match typical Herx symptoms you've researched, it remains a possibility, especially given your history of Lyme disease. A Herxheimer reaction is an immune response to toxins released by dying bacteria, often triggered by treatment but potentially by severe physiological stress. Symptoms can include fever, chills, nausea, vomiting, headache, rapid heart rate, low blood pressure, muscle pain, and an exacerbation of existing Lyme symptoms. The extreme physiological stress of a 7-day dry fast followed by refeeding could theoretically trigger an unusual or exaggerated immune response if residual Borrelia bacteria are present and impacted by the metabolic shifts. A Herxheimer reaction is a temporary flare of symptoms that can occur when treatment starts killing off bacteria faster than the body can clear them, leading to symptoms like brain fog, headaches, joint pain, anxiety, fatigue, or flu-like symptoms.
Common symptoms of Herxheimer reactions can vary but often include fever, chills, nausea and vomiting, headache, rapid heart rate, low blood pressure, hyperventilating, muscle pain, skin rashes, and flushing.

6. Vagal Nerve Dysfunction: The vagus nerve plays a critical role in regulating numerous bodily functions, including heart rate, digestion, and the body's stress response. A sudden and severe reaction to intake, particularly with rapid onset of symptoms like dizziness, nausea, heart racing, and anxiety, could indicate an acute dysfunction or overstimulation of the vagus nerve. This could be part of a broader autonomic dysregulation. Conditions associated with vagal nerve dysfunction include fast or slow heart rate, high or low blood pressure, digestive issues, chronic fatigue, and chronic headaches. Fasting and refeeding can impact vagal tone. The vagus nerve transmits a complex array of messages between the brain, digestive system, and organs. When the vagus nerve doesn't regulate bodily functions as it should, it's called vagus nerve dysfunction, which can manifest as a sudden drop in heart rate, fainting, fatigue, blurred vision, sweating, or ringing in the ears.
Considering Your Specific Points:

"CT scan of my head and my blood test was good": While reassuring for immediate life-threatening structural issues (like brain edema) or gross metabolic derangements, standard emergency blood tests might not capture subtle or rapidly changing electrolyte imbalances (especially intracellular ones), specific inflammatory markers relevant to MCAS, or functional dysregulations of the nervous system.
Reaction to minimal water/food: This is highly unusual and suggests an extreme sensitivity or a profoundly destabilized homeostatic system. It underscores the severity of the physiological disruption.
Anxiety: The sudden, severe anxiety, particularly when you've never experienced it before, points strongly to a physiological trigger rather than a primary psychological disorder. It's likely a symptom of the body's acute stress response to the internal dysregulation.
Vaping nicotine: While nicotine can affect heart rate and blood pressure, and withdrawal could cause some anxiety, it's less likely to be the sole or primary cause of such extreme and specific reactions to water/food. However, it could be a contributing factor or an additional stressor on an already compromised system.

Urgent Recommendations:

Given your inability to safely consume water and food, and the escalating severity of your symptoms, you are in a critical situation. You must return to a hospital immediately. IV hydration and careful electrolyte management under medical supervision are likely necessary. Inform the medical staff about your entire fasting and refeeding protocol, your history of Lyme, MCAS, and POTS, and the precise nature and timing of your symptoms. It is vital to seek care from medical professionals who are experienced in complex metabolic and autonomic disorders. This may involve specialists such as an internal medicine physician, an endocrinologist, a neurologist specializing in autonomic disorders, or an immunologist/allergist.

Your body is signaling a profound disturbance. While your prior fasting experiences may have been successful, the combination of a 7-day dry fast followed by refeeding appears to have triggered an unprecedented and dangerous response in your system. Do not attempt to self-manage this critical situation. Your health and safety are paramount.

Re: In dire need of Help: Strong reactions to water/food during refeed

Post by Yannick »

I wanted to provide an update on a member’s recent refeed crisis, as I’ve been in direct contact with him over the last 2 days during what was clearly an acute emergency situation. (this is a summary of our disjointed conversations)

For context: after completing a 7-day water fast immediately followed by a 7-day dry fast (14 days total abstinence, 7 fully dry), he began a careful refeed (modified Filonov-style, starting with kefir and slow-sipped water, minimal sodium). On refeed day 3 he developed severe, rapid-onset symptoms triggered by even tiny amounts of fluid: extreme dizziness (orthostatic component), tachycardia, hot flashes, sudden intense anxiety/panic, head pressure, nausea, brain fog, and later skin crawling, visual/auditory distortions, and a profoundly altered mental state. Symptoms lasted many hours and progressively worsened, making normal hydration/eating extremely difficult. Hospital workup (CT head, bloods) was essentially normal aside from low-normal potassium and sodium.My assessment after reviewing everything in detail:
This appears to be a multifactorial crisis:High risk of refeeding syndrome–like electrolyte shifts, strongly amplified by the water-to-dry transition (which is generally taboo at longer durations — it disrupts RAAS, accelerates electrolyte depletion, and sets the stage for severe refeeding complications).
Possible acute endotoxic / Jarisch-Herxheimer–type reaction (given his confirmed Lyme history and prior MCAS/POTS).
Liver processing overload (exacerbated by supplement stacking, prior rare benzo use, vaping, and the extreme metabolic stress).
Energetic/metabolic crisis (body struggling to switch fuel sources properly).

The 7-day water → 7-day dry sequence is something I’ve never seen attempted at this length — most people would run into serious issues, even if the dry phase itself feels tolerable. Transitioning dry → water is generally safe; the reverse is not, especially beyond short durations.Positive update (refeed Day 6–7):
He reported a clear turning point yesterday evening. After introducing pure potassium chloride (slow-sipped, ~1g elemental K over hours), magnesium glycinate, continued high-dose B1 loading, TUDCA, and — most importantly — switching entirely to coconut water, diluted fruit/coconut juices, ripe bananas, watermelon, and soft fruit/veggie soups, the severe symptoms began to lift markedly.

Key improvements:
Skin crawling/burning/tingling resolved
Anxiety, hot flashes, dizziness significantly reduced
Able to tolerate food and fluids without massive flares
Dry mouth gone, good urine output
Nervous system calming noticeably
By late evening he felt well enough to go out on his scooter — a huge shift from the previous days of constant distress and mental breakdowns.

He’s now focusing on natural potassium sources (coconut water, fruits), avoiding plain water and aggressive supplementing, and taking it very slow.Take-home points for the community:Do NOT transition from a longer water fast directly into a longer dry fast. The risks skyrocket.
Refeeds after extended or aggressive fasts should prioritize coconut water/fruit juices early — plain water can be problematic.
Pre-existing conditions (Lyme/load, prior medications, etc.) + over-supplementing can push the liver past its capacity during metabolic stress.
Recovery, when it starts, can feel sudden once the right combination of gentle electrolytes and energy substrates is found.

He’s not fully out of the woods yet, but the trajectory is now clearly upward. I expect steady improvement over the coming days if he keeps it simple and gentle.

Re: Horrific reactions to water during refeed

My god am I glad to hear there is some improvement here. I was genuinely worried, and even more worried if the ER would recognize everything going on.

A word to the wise: B1 repletion can take several months(edit: to complete 100%, not to see improvements).
Certain forms of B1 like TTFD or sulbutiamine can sometimes be needed.
edit: If your B1 is something generic like thiamine.hcl, 100mg is not that big of a dose yet, even tho it is large compared to the recommended daily intake.
I just got a stack of TTFD in the mail and kinda wish I could give you half of it to get fully stable. It really is much better, in my experience.

If you are this close to severe clinical deficiency and vagal dysfunction, realize that any stress can deplete your already small stores quite quickly.
Easier said than done, but the calmer you can stay, the better.
Usually people would have a reserve to buffer stress, yours may be near non existent.

Stay in touch with us all, and keep us updated. You will get through this, I promise you.
I know it can quickly feel overwhelming and hopeless in the state you are in, but you will recover.
We already know something you did makes this amenable to treatment. Now it's "just" fine tuning it.

- starting to get symptoms of having the need to do deep breaths. Not hyperventilating, but just deep breaths all the time
If you get this need to do deep breaths after eating, it could be that your metabolism is increasing a bit, creating more CO2 from burning the carbs.

If you also have been very stressed, your body's internal set point for CO2 could be lowered dramatically, causing you to feel the urge to over breathe.

Now I know it sounds counter intuitive, but if you can maintain a light to moderate "airhunger" for 20 minutes, by doing Buteyko/OxygenAdvantage breathing, that might help you recover your metabolic rate and health.
Basically you breathe light to breathe right. Youtube has many videos on how to easily learn this. Patrick McKeown's from OA are my favorite.

Hoping you are seeing this, and that your health is trending upwards.

Titan, you cannot believe how much it means to me that you are checking up on me and keeping track with my thread.
This experience has been very isolating and very very hard mentally. I didnt reach out to friends and family as i just know they would suffer seeing me run around in my room like an animal in a cage.
Seeing a complete stranger on the internet take interest in my well being literally makes me break down in tears. Right now, you and yannick are the only people who know what im going through. Thank you so so much for that.

I am reading and listening to every word you say.
- I bhought thiamine way back, to fall back on in case i suspected a refeeding syndrome during a water fast. It obviously never happened. I started taking it as soon as you made your post and that was a good call.
- Its Thiamine Mononitrate, so a salt (weak bioavailability)
- i just watched a bunch of videos from Elliot. Seeing how B1 is connected to many things that might effect me right now tells me its a good idea to load up on it
- He recommends dosages on how much to take for each form. He says one should start slow and increase dose as time goes on. Unfortunately i couldnt find information what starting dose i should use for each form, just an overall recommended dose for each form
- The paradoxical reaction to B1 might be mitigated when specific other minerals are taken. I have taken note of them and ill be ordering them now.
- I will try to find a source for TFFD
- You are right, it does seem my metabolism is increasing.
- I will look up Buteyko/OxygenAdvantage breathing and try it out tomorrow, as i am certain i will have to endure halph of the day with my symptoms once i sipped my coconut water

Thank you again, for saying these words to me. They are really everything i have right now to make this through. I am giving my best to get me out of this hell-hole, but it has been very hard while the symptoms were slowly chipping away at my confidence and my mind. Thank you.

You are very welcome. I think a lot of us in the dryfasting community have tried the feeling of no one understanding and feeling like there is no way out.

www.objectivenutrients.com/eu
have the TTFD that Elliot is talking about. It's his company too, made because TTFD and such are so hard to find.
They also have a bundle option, where the cofactors can be bought along with TTFD.
If you get TTFD or even other B1 than mononitrate, it's best to start as low as possible, and gradually increase. For TTFD, that might mean 10-25mg, an eighth to a quarter of the 100mg capsules. as they are that much more bioavailable and thus potent.
This is important, because the higher the dose, the higher the electrolyte requirements and the worse the paradoxical reactions can be.
It might be a few days of your symptoms going up and down, I know that sucks very bad and it can seem appealing to do a large dose of TTFD, but if you run out of electrolytes completely, you could be done for. Better to go too slow than too fast.

Wishing you a better day tomorror than the last few ones.

Re: Horrific reactions to water and food during refeed after 7WF -> 7DF

Post by Titan »

17:15):
- no reaction to last food/water so far
- todays episode/crisis has indeed ended very soon today
- expecting this pattern to continue over the next days until it has stopped completely
I think I'm about to set a world record for longest sigh of relief.
So good to hear you are doing better.

Am also very glad Yannick caught this early and stepped in to guide you out of the woods.

Only thing I can add at this point is, someone as hard charging and will strong as you probably wont like how much patience it will take to fully regenerate metabolism and replete B1 stores. Can take months (doesn't mean you will suffer that time).
If you stress yourself out, it can reverse things.
If I can shortcut your learning about B1 from what Elliot Overton has taught publicly, I'm happy to answer any questions.

I think you have got this under control now.
Do stay in touch anyway, whether things get worse or better, and keep up the good work.

Thank you, Titan, for keeping to check up on me. Today (Day 8) has been really a clear sign that things are going to get better.

And you are absolutely right, this will take some time. I have done a stupid amount of water fasting this year and i had zero issues recovering from it.
I had 3+ months of total water fasting this year and i couldnt even tell.
But this 7WF + 7DF has tanked my metabolism to levels that its having a very hard time adjusting back to normal and my nervous system is reacting in a way that is very unique it seems. I dont think anyone has come out of a extended dry fast and reacted this badly. Obviously you can make mistakes during a refeed that will have side effects, but not this. This is just random.

I know it will take atleast another week (sigh) to feel like myself again and i know its going to take months to fully restore my metabolism and restore nutrients/minerals/vitamins that i have depleted through this traumatic experience.
It will also take time for my nervous system to heal.

I will abstain from any kind of fasting for quite a good of time and fully work on coming back to health after this ordeal.
I am not in the position to harm my nervous system like this again.

I will research more about B1 therapy and how to do it. Right now i have this to say:
- I was about to jump start this B1 therapy in order to get out of this nightmare, but i think ill start slow
- I know other B Vitamins are crucial if this is supposed to work
- B1 increases demands for B2
- B2 doesnt work if there is a iodine, selenium, and/or molybdenum deficiency
- Before i know more about dosages, ill keep it at 300mg (split in 2 doses) of benfotiamine for now. What do you think about that?

I would very welcome if you can give me a very simple rundown on the most important things to consider with this B1 therapy.
I will probably have to stick to benfotiamine.
