Hi, K9ja. I take the same amount of Mestinon as you. I used to take 5 a day. I do not experience double vision. But I am with you on the not being active part. It is so depressing. I was diagnosed 2 years ago and have put on 20 pounds and I don't take prednisone.
I was a high school coach and very active, now I have no energy. After a short shopping trip, I need a nap. I never used to nap.
