Jinx, you should tell your family to read this website and a few others about mercury from amalgam fillings. Many children are familiar with the fact that mercury causes psychological problems.

As for cognitive probrems, I have had some which got better or worse at times. I am still amazed by the fact that I had mercury amalgams in 24 of my teeth, and that 15 or the amalgams were quite large. I had almost all of these for over 20 years.

Perhaps you should tone down your chelation. Take it slow. There is no reason to rush it, especialy if it is causing bad side effects.How many amalgams did you have, and how long did you have them?
