I don't take anything for my MG other than the mestinon because if there is a side effect, I get it. I am hyper-sensitive to meds and have to take benadryl with everything.

You say you have lung issues, have you been tested for Alpha-1 deficincy?

Alpha-1 is a lung/liver issue and it a missing gene, something about your liver doesn't produce something that protects your lungs. I still don't understand it completely but it is always worth a look.
