I have always been really sensitive to most meds too - - and have to careful whenever I start something new since I'm never sure if I will have a reaction.

When I was given a 'test' dose of Mestinon the first time, I felt like I had drunk way too much wine! It took about a 1/2 hour to get rid of that feeling, but then I felt great!

Initially they said it was too bad I couldn't take Mestinon! I argued to try a lower dose ... and it has worked for three months now!!

I literally have two bottles -- one with 60 mg pills that I have quartered and one with 60mg that I have halved. I 'know' when I need which dose by how my body feels. And it's a bit of a pain to have to take the meds so frequently, but I have had NO side effects (and no 'wine' brain!).

For me, I feel like my body doesn't tolerate 'normal' doses of any drug - - I mean I only take one ADvil for a close to migrain headache! Maybe this would work for you,,,,hope so.
