Greg,

That sounds like a pretty classic list of MG symptoms. Ask your Neuro if you can try Mestinon, just to see if it helps. If it does, then that is another indicator of MG. If it doesn't, or makes you worse, then you should perhaps look for a different diagnosis.

It is at least a drug that acts quickly (30mins) and is out of the system fast if it is inappropriate. (4 hours)
