Many people can not tolerate Prednisolone or the immune suppressant drugs so they can only take mestinon.

For me Im stuck with mestinon only because I can't get anyone to diagnose me, despite the fact my symptoms are pretty classical MG.

Ive been stuck in this position for a couple of years after the initial diagnosis of MG was withdrawn. At this point Id try anything to get well. My illness affects me to such an extent I have only been out of my house three times since the end of August.

Love
