Don't worry so much about having 2 fillings replaced. I had 25 mercury fillings replaced! What are you doing about the the parasite infection? How are you treating that? Make sure to treat it for long enough, otherwise you won't get rid of the infection. In addition to the prescription drugs or wormwood/green black walnut/cloves, you can eat raw garlic(one section after each meal), and take cat's claw and olive leaf extract.
