Lizzie!
I am so glad you shared that about Mestinon wearing off and twitching. That's exactly what has been happening to me - and I was getting confused!!

I felt like I needed more Mestinon (and the timing was about right) - - but my neuro said that too much Mestinon would cause twitching and should be watched out for so as not to overdose.

Yet once I stared taking a half dose (at first sign of twitching) ... every single time the eye twitching stopped as soon as the Mestinon kicked in.

So thanks Lizzie for letting me know I'm not the only 'snowflake' with this particular bent!! lolol
