davew, I've read mestinon does not work for everyone with MG. (I think I read only 50% get a lot of benefit from it.) It absolutely works for my MG but I will say that it doesn't always work 100%. On a good day with mestinon, you can't tell I have ptosis. Then, there are days when I am run down or under stress when a full dose of mestinon won't fix the ptosis 100%. This summer I was taught a few harsh lessons about MG and heat. Mestinon might have helped, but it wasn't very obvious if it did.

Anyway, I do feel gr8ful mestinon helps as much as it does. When it works, it's like a miracle.
