Hey there! Sorry you’re having those issues, side effects are really frustrating. I only take mestinon as needed, which for me isn’t very often since it doesn’t help me that much (bummer) and I have massive side effects, including:
– dizziness (so much so that I’m almost non-functional)
– nausea
– muscle twitching
So I feel you with some of those side effects. My neurologist was also unconcerned with the side effects, but yeah I get how they can be scary. Maybe ask to speak to a pharmacist for more input?
