Joanmarie, I can only imagine what it's like to have to try a drug you haven't been on for awhile that might make you really sick. Maybe you could try the Mestinon syrup. That way, you could start out with a very small dose and work your way up. Maybe your body would get used to it better.
I know what you mean, most days I feel like a hermit. And crabby.
I hope it all goes well. You need to feel better.
