I was diagnosed two years ago. I started with bad symptoms three years ago.

I take Cellcept 1,250 mg per day.

I take mestinon (generic) 60 mg up to 5 X per day.

My original symptoms included:

Falling
Shortness of breath
ptosis
double vision
difficulty speaking (hoarse or non-existent voice)
difficulty swallowing
nightmares (probably because I couldn't breathe)
fatigue

My symptoms now are:

ptosis (not as severe until night)
weakness in my legs (but I don't fall over)
shortness of breath on exertion
fatigue

I'm by no means totally well, but my condition has improved so that I can walk, talk, and eat, and breathe. I will admit that I walk kinda funny....
