I take 60 to 90 mg of Mestinon, depending on my weakness level. Years ago when I was first DXed with the MG I was on 120 mg every 4 hours.

So to me 60mg is not alot but we are all different. Talk to your Dr. if the 60mg is helping slightly, talk about uping it to 90mg and see what happens. As you will learn with MG things are trial and error so to speak.

I wish you good luck and continued strength.
