Hi, Sam. I'm glad you don't have any obvious symptoms now. But what if you rapidly get worse? If it were me, I would like to have at least one drug for the disease I've been diagnosed with on hand "just in case." Like after you run that half marathon. What if that is the trigger that kicks your MG into high gear? Your body gets heated up during exercise and heat makes MG much worse. Just be careful. Some MGers have gone into crisis, where they can't breathe well or speak, and they could not tell someone what was going on! At least carry a small "medic alert card" in your wallet/back pocket saying that you have MG and the name/number of your neurologist. What else is usually on a card like that is an emergency contact (like family), insurance information, drugs you are taking, past surgeries, other doctors, etc. Just write some stuff on a piece of paper. You can laminate it too, getting laminate from an office store, in case it gets wet and no one can read it!

I hope the marathon goes well.

Annie
