Hey Draggin',

Welcome to the group! You can build up a tolerance to Mestinon, but I don't know if this is the case with you. Some neuros will have their patient stop it for a short period of time and then start it again. Since this is something new for you, the best thing you can do is call and inform your neuro. Please let us know how you make out and glad you joined the group!

Hugs,
Pat
