I took my morning dose (9:20 am) and it made me extremely tired and weak. After it wore off I felt better. I'm not having a bad day weakness wise so I could notice the difference when it wore off.

I took the second dose at 4:20 pm and the same thing happened. My arm and neck became extremely weak, I couldn't grip with my hands. I tried to rub my dog and my arm wouldn't go all the way up and it's like my hand just fell on her, couldn't grasp her fur because my fingers were weak. The weakness has eased up some but my sister noticed it as well.

I've also noticed that Mestinon makes me feel like I'm drugged up and tired. I'm not sure if I should take the 3rd dose or not. Now I'm concerned that MG might not be the problem which just puts me back at square one all over again.
