Interesting, thanks for the information. I'll have to present this evidence to my doctor. So far, I must say that over the last few weeks, I do feel slightly better, but nothing earth shattering (which is to be expected, given my fillings are still in). I am due this week for my "down spell", which occurs in almost precisely six-week cycles, so we'll see what happens. Unfortunately, I don't have the cash (6 to 8 grand) to have my fillings replaced, and I admit there is still some lingering doubt about my case (not about mercury poisioning in general though). If I had the cash, I wouldn't think twice, but times are tough. Anyway, thanks again for the info.
