Almost all games will do this. Watching TV for extended periods of time will do this. There's a warning in the first couple pages of most video game manuals concerning it. Read that mofo.

Pretty much, it says play the game. Feel weird? Take a break. Still feel weird? See a doctor.

To answer your question, no, I've never felt nauseous from gaming without actually being sick to begin with. I do have small muscle spasms every now and then but that could be because I don't eat enough bananas.
