Sounds familiar. I don't know if I have mercury problems. I do have a nickel problem though. (Hair test) I went to a Integrative MD and he said I have adrenal fatigue. In fact I have all of your symptoms, I thought it was one of my old posts, except mine all happened recently when I lost weight intentional, you know they say heavy metals hide in fat and BAM I got it. Treating my adrenals has helped incredibly. The problem is and Russ will vouch for this is that mercury effects EVERY cell of your body. EVERY cell of your body needs thyroid and adrenal hormone. Heavy metals love glands too and basically the mercury takes the parking spot of a receptor or a a part of the gland that should be making hormone or receiving messages.
