You'll probably notice some similarities between my posts above and the one in that link because I wrote them both;)
I'm glad people are reading that! I strongly think there is a connection and it seems many on this site feel the same way.
Though amalgam fillings are probably the biggest culprite, there are other ways to be exposed to mercury. The other big way is through immunizations and flu shots. They contain a preservative called Thimerosol, which is 50% mercury! Google Thimerosol and read for yourself. Many belive it caused OCD and Autism in a lot of people (especially children). Seafood also contains a lot of mercury.
