Nan,

Maybe you should try scaling back to 60mg every five or six hours and see how that works for you. Too much Mestinon can cause problems, just like not taking enough. I too feel stronger since starting Mestinon, my endurance has not improved as much as I had hoped, but I do feel a difference overall. My legs still get very tired if I stand to long, yet climbing stairs has improved. My arms don't wear out as quickly, I still have trouble doing some repetative tasks, there are times when I can hardly scramble an egg!

In a nutshell, if I overdue it I wear out period! But overdoing now is nothing like overdoing before. I'm not sure if stopping the Mestinon all together is the answer, it might just take a bit more experimenting to find the right amount.

Let us know how things work out,
