Oddly enough, no. I did feel quite ill during the scene in Snakes on a Plane where the snake comes up out of the toilet and bites the guy in his special place, though. That was nasty. I do sometimes feel ill if I play a game for way too long, but I've never been reduced to actually vomiting. I suppose if I were forced to play a horrible game for a very extended period of time I might.
There was one movie I've seen which could have justified vomiting, though, and honestly, vomiting would probably have been the best way of expressing how I felt about it: Eragon. Leaving aside the fact that it's just a copy-paste job of Star Wars and LotR, it's still a horribly incompetently made film. The acting is mediocre, the special effects suck, and the film never stays in one place for more than about five minutes, resulting in no character development to speak of, and the plot being a nonsensical mess. It was horrible.
