Thanks, Erin.

FYI: I had a pulmonary function test over the years, and it shows that my breathing is better. Of course, I'm not lying down, when I take it.

Plus, I have had sleep studies. No problems. I sleep like a baby w/that thing on at night. LOL.

Anyway, I feel as if it's muscle weakness that is causing this. As a remedy, the doc told me to take 180 mg of Mestinon at night and follow up with a 60 mg in the morning. It works for the most part.

However, the other night w/in 2 hours of taking 180 mg of Mestinon, I felt my torso, especially around the chest area, feeling as if was being weighed down, so I took 60 mg of Mestinon. There were no problems at night.

Does this sleeping issue mean weak muscles? I just need to hear from people out there, because the docs can't pin point any other cause.
