Try one-half an immodium before you board the planes. And if I were in your position I would just go ahead a get some adult diapers. It might help just to know you have them. My doc gave me an Rx for an anti-anxiety drug, but I don't think it made me feel any different.
I sympathize! I have to fly quite a bit. Small planes are torture. So was that period when you absolutely had to stay seated for 30 mintues flying into D.C. Relax, Breathe, but don't sleep because you know what happens as soon as you wake up!
