after a 17 year remission I am once again symptomatic. I am taking 60 mgs of Mestinon every 2.5 hours. does anyone else take that much? I am also on 20 mg of Prednisone. Years ago the Mestinon seems to have worked better for me. My swallowing seems to be getting more difficult. I can still swallow but it is beginning to feel like stuff is getting stuck in my throat while eating.
