Tracy...It is so frustrating to be going through this. I'm sure that it's not much of a comfort, but I'm glad that they found a cause. Now if they can only treat it completely and effectlively. No need to every apologize for feeling down. Mercury toxicity is enough to go through, let alone the other health problems you have had to deal with. I agree, it's sad that dental work has done this to you but I believe it.
