I must be one of the lucky ones, at least so far. Mestinon 60--3 x day, has virtually ended all my symptoms. I have a small problem chewing sometimes, but not at all like it was. Eyelid problem gone instantly. Only been 3 or 4 mos so far, so hope i'm not speaking too quickly. No thymus problem on ct, but high count on antibodies. Anyway count me happy so far.
