next time you talk to the doc , you may want to feel him out on the mercury issue ( for example ask him what does he know about mercury poisoning , this single question will answer many of your own about his veiws on the subject without putting you on the spot and avoiding him catogorising you as a problem paitent, I found out alot from my old doctors just with that simple question and had to sort through a few doctors before I found one that actually recognized the symtoms and was able to help me instead of waste my time
