Hi Tex. I also have very similar symptoms as you do, and I think what set me over the edge was also eating too much tuna. I had other things that led me along the way (an MMR shot when I graduated college and six amalgams as a child), but in a six month period of time, I ate A LOT of tuna which I think was the straw that broke the camels back. I had no idea about mercury in the tuna at the time and thought I was controlling my hypoglycemic symtptoms by eating it very frequently. Within that year , I developed all of the symptoms that you have and have had them since. In my case, my hair test, blood test, and urine test with a chelating agent all showed about 7 times the acceptable level of mercury for a woman of childbearing age. I have not removed my amalgams because of fear that I would get worse (some drs told me I'd get better, others said that I would get much worse), but I have tried everything and am not getting better over time - lately worse. I think you are on the right path, and I am convinced now that I will not get better until I get the amalgams out and find a way to chelate.
I wish I found this forum back then - I'm we all have it now.

Good luck and keep us posted as to how you are doing.
