As long as I'm speculating wildly, I just remembered that my first MG symptoms hit me when my five youngest kids all had the swine flu at the same time. I never got it, but I was exhausted taking care of them. Maybe my immune system's response to the virus set off my MG, and it had nothing to do with my thyroid.

Anyway, I just read something I hadn't known: that the Graves' antibodies attack the receptor cells in the thyroid that bind to the thyroid stimulating hormone. Sound familiar?
