Had it for appx 35 years, but think it started as far back as high school ( I am 73). Mestinon, Plasmapheresis , IVIG can keep it generally under control. Impact on breathing is a significant issue. I have stopped breathing at night more than once. Weakness is a constant along with muscle pain, and flair-ups can put you down for a while. But you can make it. Check out the MG group on Facebook. Good luck
