Oh man!! I think this may be the cause of my problems. The last few years I have been suffering from brain fog, acne, and my nose is always stuffed. I've been doing all types of research and tried gf diets, removing sugars ect. I have over 5 metal fillings that are quite old. I am also very allergic to certain metals. Certain watches and jewelry will give me a horrible rash. I may get these poisonous things out of my mouth!! I'm keeping my fingers crossed!!
