I forgot to mention, I did get helicobacter pylori last year, and am only just starting to recover. I'm not saying they are linked, but the medicine that the doctor gave included a drug that affected potassium. Interesting.

2nd edit: I forgot mention as well that I haven't taken any supplements, like electrolytes for months, due to my h pylori issue. So the BFS symptoms seem to have gone and without the use of supplements.

Anyway, good luck all.
