I was very lucky in that I got diagnosed very quickly.  One Saturday morning I was driving with a friend in my truck, my eyelids kept falling. I wasn’t falling asleep since we were conversing.  Monday, I scheduled an appointment with my primary care doctor.  Later that week, at my appointment, I explained that several months earlier I took my wife out for a nice dinner and could only eat 1/2 of my steak, my jaws got tired.  Then a month later we went out for a Sunday brunch at a fried chicken buffet, I could hardly chew the chicken.  Then I told him about the eyelids and he just said “Myasthenia Gravis “.  My response was “back at ya doc.”  He had seen two patients when he was an intern that had MG.  The blood test confirmed his diagnosis.
