I wonder if they are not detoxing you to quickly. You sound sicker than I do and I have 11 amalgams in still. Not every method of detox is going to work for everyone. You have to find what makes you feel better and that may be a more natural route. But, yes how did you mercury get that high with only one amalgam? Hmmm?
Have you looked into detoxing naturally? Using Chlorella and other supplements?
