Welcome Seacoast - glad you found this forum. You will find that we are all quite different in the way MG effects us and our lives. For me, in the beginning, I experienced fatigue of specific arm muscles ... and not much else. Gradually it has progressed to weakness in legs and neck at times, but not general fatigue or tiredness. And I have no eye involvement.

Re: Mestinon
For me, small amounts more frequently is the trick. In the beginning, I took a tiny amount (15mg every 4 hours), now I take 30 mg every 3 hours. I tend to be quite sensitive to most medicine... but every one is different and with Mestinon it can take a while for person to find the best combination of amount and frequency. This has to be done with your doctor though - not experimenting by oneself!
