I wanted to add that a full pill (60 mg) at a time gives me double vision and so I generally take 30 mg every 4 hours during the day.

I had double vision with MG that did not go away until I had taken Mestinon for 5 months. According to my doctor, and me from experience, there are benefits from taking Mestinon long term such as a reduction in double vision.

Sometimes I take 30 mg Mestinon every 3 hrs when my symptoms get bad. And when the MG isn't too bad, I take 15 mg every 4 hrs.

Too much Mestinon can make me just as weak as not enough, so I suggest trying out different dosages and times between pills to see what works for you. Of course, talk to your doctor so that you have limits. My doctor has given me the ok to take any amount between 15 mg and 120 mg per day at whatever times work best for me.

I try to take a steady dose every day, but sometime I have to adjust it when my symptoms increase or decrease.

I hope this helps.
