My hubby has a tender digestive system, but the Mestinon for him had absolutely no side effects (okay, except once when he took two, forgetting that he'd already taken one - major diarrhea). The best part was when he could finally swallow his dinner without any surprises. Now, a year later, he still has no side effects, and can some days take only two doses without any issues.

Here's hoping you have a similar experience - just make sure you don't take two at one time!
