Bex. Yes, I tend to believe that mercury in itself doesn't cause much of the painful symptoms, except that it messes up body chemistry, and lets candida and other pathogens mess you up further, and these make it a long lasting experience. But this is only my opinion.
My own experience doesn't support the idea that mercury would directly cause anything -after amalgam removal-, but I guess this is different if you have loads of fillings - I had only one. However, I have also been ill, lots of adrenal fatigue, blurred vision and all classic mercury-related symptoms.
Regarding the use of antifungals or mercury chelators: we have seen both cases: some people here have only found relief in using anti-fungals instead of mercury chelators. And the opposite. Which is which? Also, do some of the chelators have a dual effect in addressing both mercury and candida like I believe?
I heard in people with CFS and Bipolar Disorder there is often a specific immune system reaction when exposed to mercury. They body starts to produce antibodies as defense and the immune system tends to overreact when it comes in contact with mercury. In those people it's not so much the poisoning itself it the immune system out of control.
