finding the right treatment can be very frustrating. My husband 's symptoms are limited to his eyes.. he had a thymectomy 2 years ago...mestinon does not seem to help alot (but maybe it does more than we think). dr started him on azathioprine last october....had total relief of symptoms after 1 week but then had a reaction to the azathioprine so had to come off. started cell cept but never got the relief he got with azathioprine but doing pretty good till the dr tried weaning him off prednisone. basically went back to square one and never has totally rebounded. we just keep praying for that miracle
