Desertflower,
I have exactly the same symptoms in the morning!!! The shaking and dizziness is scary!!! Do you also feel nervous and anxious like you are in overdrive? I really thought these symptoms were related to the antibiotic I was on but i have been off of it for 3 days and still feel this way every morning. I had a CBC done yesterday and know if everything there comes back fine it HAS to be the Mestinon. I think I am like you and do better with less and don't seem to need it at night. I take my first dose late morning but by 2:00 I can definitely tell I need my second dose. I start getting very weak feeling.

I am going to work on drinking more water. I think that may be part of my problem. Maybe that will help with some of the shakiness and dizziness. Thanks for the tip!!!
