Hi, Catch. When I was dxed with full-swing ON I was about to take a business trip. I DID wind up canceling the flight but only because my neuro-ophthalmologist had managed to get me an appointment with an MS specialist in record time and I would have had to re-schedule. She didn't want me to leave town for this reason but she also said that if I did take the trip "nothing bad will happen".
Actually, now that I think of it I guess I should add that 2 weeks prior to this (at which time I didn't have a CLUE as to what was going on) I flew in and out of town on a short trip. And nothing bad DID happen.

(Except that I was driving around on highways not knowing what I wasn't seeing!
