Thanks Sunshne. I think that post by Andy explains why I can only take one pill of the stuff. My doc said take two, but I can't. Two makes me cry, get emotional, etc. and REAL spacey, while one is just right. Actually, I am thinking about taking 3/4 of the one and see how that works. But it does help with energy levels -- A LOT. I tested for very low sulphur and it seems I just cannot eat enough to get the energy levels up.
