I'm only newly diagnosed with MG - been on medication for about a month. I take 20 mg prednisone once a day, and 30 mg of Mestinon three times a day. I noticed improvement the second day of being on meds - I felt like superwoman! Maybe it was the Mestinon? I don't feel like superwoman now, I just feel fairly "normal".

But then, my neurologist tells me that my MG isn't a very severe case. Maybe that has something to do with the quick reaction?
