Motion sickness, from what I've observed, is sort of an acquired taste. By that I mean that it can be overcome by repetition. As an example, way back when I was going through Air Force Pilot Training, we had a fellow who, for at least the first 30 flights, threw up on each and every ride. He got so good at it that he'd stuff a barf bag in the left sleeve of his flight suit, and hold it there with the velcro adjustment wrist strap. Then, in flight, when he needed it, he'd pull it out with his left hand, hold the bag in front of the cool air outlet (if there is such a thing on the T-37) to inflate the bag, drop his mask, barf into the bag, spin it around to seal off the top, and finally stick the bag into the leg pocket of his flight suit, then replace his oxygen mask and continue on his merry way. He actually turned out to be a real good stick. So, don't despair, you can overcome it. My bud was lucky in that his IP felt he'd do fine and so he wasn't turned in to the flight surgeon.

Good luck.
