I used to get something like that from playing Halo.
I always went back to playing, and over time I developed a tolerance for it. Otherwise, I would imagine a sea sickness remedy would work. The following is a link I found, along with the critical excerpt from it.

Medications
Medications for motion sickness may cause drowsiness and impair judgement and, therefore, should be avoided in pilots, astronauts, ship crew members, and individuals in any other occupation where heavy equipment is operated or where being alert is critical. The following medications are a reasonable option for infrequent travelers and others who experience motion sickness occasionally:
Scopolamine—most commonly prescribed medication for motion sickness; must be taken before the onset of symptoms; available in patch form that is placed behind the ear 6 to 8 hours before travel; effects last up to 3 days; side effects may include dry mouth, drowsiness, blurred vision, and disorientation
Promethazine—take 2 hours before travel; effects last between 6 and 8 hours; side effects may include drowsiness and dry mouth
Cyclizine—most effective when taken at least 30 minutes before travel; not recommended for children younger than 6; side effects are similar to scopolamine
Dimenhydrinate—take every 4 to 8 hours; side effects are similar to scopolamine
Meclizine—most effective when taken 1 hour before travel; not recommended for children under 12; side effects may include drowsiness and dry mouth
Good luck.
