This is a tricky disease. It's typical for it to have ups and downs. You might be having a flare-up that's not related to the Mestinon dose.

Mestinon can make you weaker if you're taking too much. But the key thing to know about this drug is that it has a short half-life. It leaves your system fast. If you were taking 60mg every five or six hours and it wasn't enough, the best thing to do (with your doctor's permission!) would be to take it more frequently, not in higher doses.

If you feel better about half an hour after you take it, but after five hours you are weak, that's a good sign that you need to take your doses closer together.
