I feel your pain. I threw up in every type of aircraft I have ever flown in, except for the F-18, go figure. I threw up on my first flight ever as a passenger of a commercial jet at the age of 5, then again on my first time at the controls of a GA aircraft at the age of 14, first flight in the T-34 and then in almost every stage while in the T-45.

I just refused to quit. I was almost kicked out of the tactical jet pipe line while in flight school because of motion sickness during the instrument phase!! Now after 1,000 hours in fighters, I can't imagine why I used to ever get sick.

Some of the things that helped me out in flight school were: not wearing gloves (yeah, yeah), staying well hydrated, eating bread before my flights, avoiding greasy foods before dynamic flights and drinking water during the flight. While flying, don’t even think about getting sick. Concentrate on the 100 other things that are going on during the flight, if you start wondering "I wonder if I will get sick on this flight", it's already too late. Don’t think about it and press on.
