yes!
Mestinon really helps with my double vision but can cause some twitching in my wrists and ankles.

I learned a great tip HERE just a few weeks ago. Mestinon can help some muscles feel better but can over stimulate other musles that don't need any extra acetylcholine.

So, now if my ankles get twitchy I just get up and walk around for 10-20 minutes and problem Solved! :-) Or if my wrists start to twitch I start doing stuff.... like house work, cooking, or laundry...lol.
