Thank you, Dawn, Bex, and Alcan. Bex, I did email that fellow twice. Perhaps I need to try again. Maybe, it being summer, he is on vacation. Yeah, the thyroid thing has me stumped. It is so difficult to find out what is the cause. It may have nothing to do with the Diamondlite, but their lack of a decent response is what makes me very cautious. Maybe, as Scarlet mentioned a while back, if not Diamondlite, holistic gold is the way to go. Trouble is, how many biological dentists do nothing but composites - they don't do any metal at all. <img src="/ubbthreads/images/graemlins/confused.gif" alt="" />
