My 2 tops meds atm are mistinon (in infusion format once a week mixed with saline) 1 hour infusion and prednisone. The prednisone for me didn't touch my double vision until it was over 25mg and then went all the way up to 70 (prior to adding infusions). I just kept getting worst and worst, until i couldn't speak, chew or swallow without constant choking. Then they added the infusion therapy, IVIG at first, which brought me back to somewhat normal, then 2 months ago i switched to mestinon infusions which seem to work a bit better than IVIG, but both keep my bad side effects at bay. Currently my prednisone is at 50, not sure how much mestinon i'm on they mix it into the infusion bag based on weight, but those are my 2 top meds. Once you find the right mix for you, hopefully you will also be back to what i refer to as somewhat normal. I just can't do strenuous stuff I used to do regularly, but otherwise i feel normal. Only BIG negative is the weight gain from prednisone, about 30 lbs for me, and tough to work it off when heavy exercise is exhausting.
