Side effects vary from nothing (me) to having diaherria. Excessive Mestinon (for your condition) can make you as weak or weaker than not enough. Most everyone finds that their Mestinon dosage is almost an art - - everyone's body responds to different degrees under different conditions.

That's why your neuro is stepping up your dosage over time. Listen to your body and you will know when you have found the optimum dosage. Be sure to share info with neuro. Most understand that establishing the proper meds for each individual is tricky.

Good luck - hope you feel stronger!
