I've known I had something since high school but the symptoms weren't too bad that was 90-91 I just altered my ability to work. Then in 05 it got to the point I couldn't pick up my new born son and that's the year I was diagnosed mg positive and put on mestinon.my family knows but I don't talk about it unless they or someone asks. Most of my friends do not know I have mg and are surprised I do cause I do all my normal activities and am considered a work-a-holic. So far the one and only crisis I've had was in the back of an ambulance and they just proped up the back that helped tremendous.
