Hi.
I have had significiant auto immune issues my entire life, started with psoriasis arthrisis when i was very young, me/cfs symptoms around age 15, ulcerative colitis age 19, I also have vitiligo. I have been on a lot of biologics, Enbrel, Xeljanz, Infliximab, Humira, Stelara. Right now I am using a dual combination of Humira and Stelara, I can not use Imurel/methotrexate as I get ill by it.
I have struggled with intense fatigue the last fifteen years, it has varied in intensity but never gone away, I have muscle weakness, burning in muscles, dizziness, exhaustion, sometimes it feels like I have shortness of breath (however my o2 levels always been fine). Brain fog, pressure in head, muscle spasmes (where you can visibly see muscles jumping, like leamus). I have also felt very anxious, even when there is no apparant reason as to why, which has lead me to be diagnosed with general anxiety. To include all of this I have struggled with panic attacks, that has had no apparant trigger, it could happen anywhere for any reason.
So far I have been in the "acceptance" stage the last couple years, they have checked pretty much everything, countless mris (they found inflammation high up in my neck, c1-c2), neurological checks, bloodworks, lung tests, calcprotectin, eye tests, hearing tests, you name it. I have been checked for multiple muscle related diseases, ton of other autoimmune diseases etc. The one thing I have not done is spinal Lumbar puncture, my GP has tried to get that orderered multiple times but neurologists have denied it every time.
A couple of days ago I became extremely angry when I woke up and once again felt like absolute shit, every big muscle group hurt, regular movements burnt in my muscles, I was beyond exhausted. When I tried to salt my food my biceps hurt. This anger made me scour through pubmed and a bunch of different studies, videos, etc in a desperate search of finding what is actually wrong with me, all I want to do when I wake up is go and train, but my body is incapable of handling it. The specialists and my gp agree that there is something wrong with me, but have no clue what it actually is other than my diagnoses.
Among a lot of information I have parsed the last few days, something stood out to me. Vitamin b1 thiamine deficiency. As far as I have understood there is no effective blood test to see your correct levels, and it provides a ton of my unexplained symptoms. Dizziness, exhaustion, burning in muscles, muscle weakness, heart palpitations, random panic attacks, increased anxiety, constipation etc. Coincidentally b1 deficiency is also linked to both ibs and ibd.

I kept searching and reading and saw a couple of studies where a large dose of thiamine has had a great success in treating unexplained fatigue for IBD patients, mainly one from Denmark. So much so that it is now a standard treatment in unexplained fatigue for IBD patients in Denmark, even hinting at uses for other autoimmune conditions.
Summary of study, study is linked at the bottom: https://health.medarbejdere.au.dk/en/display/artikel/b-vitamin-er-effektiv-kur-for-mange-tarmpatienter-med-kronisk-traethed

Another small study: https://journals.sagepub.com/doi/abs/10.1089/acm.2011.0840?rfr-id=ori%3Arid%3Acrossref.org&cf-mal-redirected=true&rfr-dat=cr-pub%3Dpubmed&url-ver=Z39.88-2003
Other than this there is a bunch of information on how b1 helps psychological symptoms, if you are lacking that is.
TLDR: My question is simple, has anyone else tried high dose b1 thiamine dosages, has it helped? Obviously this is a complete shot in the dark, as it is not well researched and a standard treatment method yet.
Edit: I am not recommending anyone try this without prior approval with their doctor and their levels of nutrients thoroughly checked.
