do all your cleanses and flushes and get your bowels and kidneys working top notch in order to remove the mercury as you loosen it up. all i have used to chelate mercury is cilantro, lots and lots of raw cilantro. and i still do it.
now that you have those fillings out, you are ready for some fasting. that will get everything out. have you read paul braggs book yet? there is a great little anecdote about mercury in there that you should read. his book is one of the top ten for health, on my list, anyway.
