Life Long Health Issues

I am one of life’s medical mysteries, although it is not at all mysterious when it is all broken down. I became sick at 37 after an unprotected mercury filling removal. I developed jaundice, my stomach fell apart, and I looked and felt grim. Every morning I woke up feeling like I had flu. I had no energy. I saw a few doctors that did blood tests. The labs showed I had elevated bilirubin and I was diagnosed with Gilbert’s Syndrome. It was considered symptomless though. I was also hypothyroid and prescribed Levothyroxine. Otherwise, I was just sent on my way.

Long story short, I removed the remaining mercury fillings safely and went through a chelation protocol. I was put on hydrocortisone for adrenal insufficiency and I developed POTS and gastroparesis. This left me pretty much housebound. After seeing a hormone specialist and a cardiologist, I slowly regained some ground and had a few good years until perimenopause. I spent many years searching on the internet about the causes of my chronic fatigue. After one too many horrible consultations with a doctor and given my family history, I self-diagnosed MTHFR, mild EDS, histamine intolerance, an underperforming gallbladder, and dysfunctional Sphincter of Oddi. This was in addition to the POTS diagnosis and B12 deficiency. It was overwhelming.

Since the beginning of my illness, I have been taking many vitamins and supplements and made real progress on some symptoms. Here, I found B vitamins to be key. I have been taking them separately, some at high doses. I have been taking thiamine in the forms of benfotiamine and TTFD, as well as B2, B3, B6, B9, and B12 along with various co-factors including zinc, magnesium, iodine, potassium, and selenium daily for a couple of years now. In terms of energy, folate and B12 were biggies, the addition of B2 did not seem a gamechanger but it was necessary, and thiamine gave me the biggest energy lift of all. It was like night and day.

I crawled all over to read case studies of people whose POTS had improved with thiamine, and worked my way up to a high dose of 900 mg of benfotiamine, or 300mg TTFD. I had some paradox early on, but was ready with the potassium, having learned THAT lesson with B12. To be honest, the paradox wasn’t as bad as I expected.


And then I pitched into perimenopause. Falling hormone levels uncovered a host of other symptoms, and so I fell headlong into histamine intolerance, leaving me with five foods I could safely eat. I became very thin and had no appetite. My POTS got worse and was especially noticeable with falling estrogen. My feet became cold and numb and anxiety went through the roof. The Sphincter of Oddi problems became daily instead of sporadic. My gallbladder had to come out. I was put on HRT and I daresay things would have been worse without it, but it was still pretty bad with it.

Covid Vaccine and Menstrual Flooding

With Covid-19 and the need for vaccines, I worried I would once again lose my health. Having read on about a young woman who had had the HPV vaccine, and developed POTS, salt-wasting, and hypersomnia, I was nervous about what a vaccine would do to all my medical issues. Luckily, because of her experience, I was aware of what could happen to a human body after vaccination and was prepared.

So when I was invited to make an appointment for the first vaccine, I didn’t think twice. I was pretty scared of Covid. I had the jab, and 5 weeks later the second. A sore arm and a headache were the worst side effects, and they were gone the next day. Just a reminder that for years before the vaccine, during the vaccination period, and after, I had continued my daily regimen of vitamins, including high-dose thiamine, as well as magnesium and potassium every day. I thought I had covered all bases against any vaccine side-effects.

A few months after the second vaccination, I had a very heavy period, unlike anything I had ever had before, with flooding and not being able to leave the house for a day. My thought then was, well, ‘perimenopause’ and ‘last hurrah’. About 6 weeks later I had another very heavy period, worse than the previous one, with the heavy bleeding going on for at least 3 days.

A Hypothesis

After my booster, a blood test that I had around that time showed that my potassium, which had been around 5, had dropped down to 3.5, which is where it had been when I began taking thiamine. My ferritin had also dropped from 50 to 30. I was feeling incredibly fatigued and breathless when I walked and needed to sleep every day.

Seeing my blood results, the low potassium in particular, made me wonder what had happened to make it drop so quickly. By then I was also getting irregular heartbeats. I realized I needed to take a higher dose of potassium, and then I remembered the case of the woman who had become ill after the HPV vaccine. I wondered if the vaccination had wiped out my thiamine, despite already being on a high dose, and so I increased it, taking 1.5 grams of thiamine HCL the first day. I took thiamine HCL because it was lying around, it came in a 500mg dose, and I hadn’t tried it before.

By the end of the day, I realized I was in paradox, my heart was racing, and I needed potassium to slow it down. The next day I took the same amount and was fine. The day after I upped it to 2 grams, and had the heart racing again. The other day I took 2.5 grams and again had heart racing. My energy has gone through the roof, the breathlessness has gone, and my brain feels sharp and alert, although it is not constant.

My hypothesis is that despite taking high dose thiamine, the vaccinations put me back into a deficient state, and many of my old symptoms came back. After reading medical studies on the relation between thiamine and estrogen, I learned that thiamine and riboflavin are required to deactivate estradiol in the liver. I believe this function was knocked out by the vaccines, and estradiol was able to build up to give me these two very heavy periods, which were completely out of the ordinary for me.

I have read that many women reported heavy bleeding after the vaccines, and some menopausal women got their periods back around the time of vaccination.

I merely pass this on as a plausible attempt to join up the dots – the heavy periods, the low potassium, the severe fatigue, and the vaccines – and this at what is already considered high dose thiamine. My conclusion is that if you have been very deficient for a long time like me, and had the vaccinations, it could take a very high dose of thiamine to restore what the vaccine may have wiped out.

  1. Unfortunately, doctors were told to forget the chemistry of the human body and listen to the ” miraculous research” of the pharmaceutical industry. They did not seem to be aware that energy is the sole requirement, as long as the DNA code was perfect. Well, we have become aware that minor degrees of genetic change are not sufficient to cause disease as a solitary, genetically determined, cause. Nutrient deficiency (fuel) plays a part. For example, type 1 diabetes has a genetic background but does not become a clinical entity until (e.g) middle age, when the person experiences a stress incident such as a viral or bacterial infection. Beriberi (thiamine deficiency) is the best example of cellular energy loss and its symptoms are those of each and every disease. The Chinese word beri translates to “I can’t and is repeated for emphasis. I have called beriberi “the great imitator”, explaining why a list of medical papers describe why over 200 diseases have been reportedly helped by using megadose thiamine for treatment. It suggests that disease is due to defective energy metabolism, with or without genetic effect or nutrient failure. Selye pointed out that energy was required to meet any form of physical or mental stress. Thiamine and magnesium together stand at the entry portal to ATP (energy) synthesis, and ” I can ‘t, I can’t” means that failure to make ATP is the salient reason for the pathological associated severe fatigue.

  2. Your dizziness, breathlessness, POTS etc, sound like EMF/radiation effects. Over the past couple years, people have been shuttled left and right to doctors, hospitals and ICUs with neurological symptoms that completely mimic the symptoms you describe – which incidentally also mimic radiation sickness – yet these symptoms are being passed off as COVID, vaccine reactions or idiopathic. We are all being microwaved at unprecedented levels. I started having dizziness in July of 2020….I woke up one morning, got out of bed and stumbled right into the wall. I thought I was having a stroke. The dizziness never went away…day after day, for months it made me miserable. And the heart racing, shortness of breath, anxiety etc…all of which were new to me and came out of nowhere. Coming into the COVID era I was healthy as a horse.

    Then after months of being dizzy and an exhaustive search for answers, I came across someone else on the internet who claimed he was having all the same symptoms, yet resolved them by buying/wearing an anti-EMF knit hat. Turns out that microwave radiation damages the little hairs that surround the cochlea within the middle ear. This also happens to cancer patients who get radiation treatments, and thus causes a similar subset of symptoms. But once these little hairs on the cochlea are damaged, they can fall out of just simply fail to function correctly. When this happens dizziness/POTS and all kinds of other bad things happen. I bought my hat from….not even kidding, 15 minutes from putting that thing on (over my ears) my dizziness vanished. I think the router in my house is probably the culprit, as it had been situated just a few feet from my head on my work desk at home.

    Anyway, I don’t know for sure that this is what you are experiencing, but it might be worth a consideration. There are several papers out there pointing out the similarities and overlapping symptoms of COVID19 and microwave radiation injury….Here are a couple..the mechanisms and manifestations are nearly exactly the same. …..
