I've learned (probably in one of the videos I included) that a LOT of antibiotics and other pharmaceuticals too block thiamine. Evidently, it is extremely common. And doctors never check for it because they think thiamine deficiency was solved by "enriching" refined carbohydrates.How many other drugs out there do things we don't know about, but their bad effects are blamed on other things?
I think I was borderline thiamine deficient before the Bactrim, caused by my Peaty diet. I eat very little meat, rely on dairy and gelatin for protein, don't eat nuts, seeds, legumes, grains because I'm strongly gluten sensitive with a pretty serious tendency to inflammation. I was supplementing with about 100mg thiamine a day before the Bactrim event but obviously that wasn't enough to protect me from it.
