I have very few side effects to mestinon, except about once a week, some minor leg cramps at night. only 1 or 2 , so it doesn't bother me that much.I take 60 x 3 a day, so guess i am lucky that I have no major side effects. I am pretty sure I have MG though, because antibodys were so high.
I hope the side effects do not increase, I don't need that
