I had one.... started chelating and a ton of problems I had as a kid are gone I didn't know was from the mercury. I can also break the diet with fairly minor reactions now. Some days I don't really even bother staying on the diet. I also pushed the yeast back a ton and went through a few weeks of horrible die off. Every round the yeast slightly comes back, so I break the diet sometimes to keep my sanity.
My ANA went from positive to negative after my filling came out. Apparently it isn't ever supposed to go negative LOL.
Though I also had a bad teeth grinding problem.....and a ton of stress. The stress may have gotten rid of my ability to properly detox. Won't ever really know.
