Mestinon DID help with my double vision but it took 5 months on Mestinon before the double vision went away.

I know Mestinon helps me for so many reasons. Mostly just because I can acually function with Mestinon. I can feel when the Mestinon wears off. I suppose I really can't feel the good effects since the Mestinon makes me feel (almost) normal. There definitely is not an obvious good feeling from Mestinon, but only the lack of bad feelings.

I too hate this expectation that, since I have medication, I should act and function normally. So far from the truth! My whole life revolves around taking Mestinon at the perfect times or everything falls apart. I am very sensitive to the timing of the Mestinon, even 30 minutes early or late on a dosage and I get double vision and weakness. And I have to take everything slowly and calmly-stress makes my world come to a standstill!

I have not tried a prism for double vision.

A 60 mg dose of Mestinon gives me double vision, so now I take 30 mg at a time and my double vision is mostly gone. This is wonderful!
