I got really sick after riding it, for probably 2-3 hours. I can handle roller coasters fine, but don't do well on spinning things like Tea Cups and the Gravitron (that should have given me a clue, but I wanted to ride anyway). I did all the precautionary stuff....I took travel sickness pills 1/2 hour before riding, didn't eat for several hours prior, kept my head back against the headrest, kept my eyes straight ahead...and it still didn't help me. As soon as the ride began, the screen appeared to be "spinning" to me and I couldn't get focus for the first 10 seconds or so. By that point, I knew ot was too late - I was sick and tears were literally streaming down my cheeks (not from crying - which I did feel like doing - but from the spinning motion causing my eyes to water). I kept yelling out at my friend and asking her if it was almost over....that being said and now that I've probably scared people, I think it depends on the individual. If you've never riden it, ride it at least once for the experience. Regardless, this is the closest you will ever come to experiencing going into space and to me, it was worth it. I'll never do it again but had I known how sick I was going to get, I would have still riden it once just to say I rode and experienced it. It did have awsome visual effects.
