Excessive sweating (Hyperhidrosis)

I've been having a somewhat embarrassing problem. I've always sweated rather heavily when exercising, but since developing MG it's gone to ridiculous extremes. For example, if I'm wearing a cap it will quickly become sodden and drops of sweat will start falling off the brim. Sometimes, even walking will start me sweating - oddly it often gets worse after I'm done with whatever activity initiates it.

It's become a fairly serious issue for me and I wonder if anybody else has experienced this symptom? FWIW, otherwise I've been mostly symptom-free since I started taking Mycophenolate in December so I haven't been regularly taking pyridostigmine, which can cause excessive sweating. I'm sort of at a loss...
