I wanted to add that I take Mestinon only and I had very bad double vision (could not read or drive at all). My neuro said that it may take up to 6 months for the Mestinon to help the double vision...and my double vision mostly is gone now and it took 5 months of taking Mestinon and also Mestinon dosage adjustments (too much Mestinon gives me double vision as well as not enough). I am so relieved to have the double vision gone. I hope you find something that helps.
