I Was Diagnosed With Myasthenia Gravis In 2003. I Have

I was diagnosed with myasthenia gravis in 2003. I have been taking 90 mg of mestinon 4 times per day and 20 mg of prednisone. I had a GI Bleed in June and November of this year. Each episode required 2 units of blood. The mestinon is very caustic to my system. I had an endoscopy each time. I am nauseous and have weak legs. I require a lot of rest. I am probably better off than most. However, I need to do something about the reason for the bleeds. When I see my neurologist, how should I be prepared?
