Hi Nicky,
I take Pyridostigmine and my bottle says generic for Mestinon. I haven't had alot of luck with it either. It does help but like you said not to the degree other people see. I am only on 60 mg tablets, have never had the syrup or the time span. When I am really weak I notice a difference but my ptosis doesn't respond to anything except the pred.
