My neurologist thinks I don't have MG, but keeps me on the Mestinon (I take 60 mg every three hours with no side effects). When we asked him if my tolerance of it (and the fact that it helps a lot) indicates that I have MG, he said no; he said that other diseases respond to it, too.

I'm not saying he's right--just that there's at least one neuro out there who would disagree with what Teresa says. Unfortunately, in my case at least, tolerance of Mestinon isn't enough to get a diagnosis. I wish it was, because I think I do have MG.
