Motion Sickness Remedies for Games?

MagikSlinger asks: "A friend of mine gave me Silent Hill 3 for Christmas (yeah, I know it's old), and I finally got around to playing it. Within 2 minutes, I had to stop and step away from the computer: intense nausea and pressure right behind the eyeballs. I got really, really motion sick playing the game. Does anyone have home remedies, set-ups, video options to make it bearable?"
