Curry.....that's a nice looking list you have there. I'd just like to add.....I know that Hep C is listed everywhere as an exclusionary diagnosis for ME/CFS, but the truth is, generally it's nothing like it symptomatically. The only people who really think the 2 diseases have similar symptoms are those who still think our disease is all about fatigue. Most people with Hep C, have nothing but fatigue....it can be profound fatigue, but still it's nothing like what we experience with ME/CFS. Regardless, the Hep C test is cheap and a good idea to have done. Hydroxycobalamin (B12) is one of the best things I have ever taken for decreasing symptoms. I take 2000mcg IM or SQ 3-5 times a week. Expensive, but worth it. True one can't get toxic on B12 itself, but I would stay away from taking too much of the Cyanocobalamin form. Lots of discussion around here on B12.
