Steve,
This is a fairly well-recognized phenomena known to the human factors
community as simulator sickness. Its source is the conflict between
visual cues and vestibular (motion and/or orientation) cues. When I
worked at McAir in St. Louis, I frequently used the F/A-18 flight
simulator for evaluations, and experienced the same problems; in fact,
there was nearly a direct correlation between the amount of actual flying
an individual had done and the degree to which they were afflicted with simulator sickness. The services have done quite a bit of research in this
area, but I'm sorry to say there's nothing you can do about it except stop
playing when you get adverse symptoms.
