I also had a terrible, horrible experience on M:S. At the time, I was 24 and completely healthy, so it shouldn't have affected me the way it did. I'm not claustrophobic -- being shut in the little capsule didn't really bother me at all. The movements and the G-forces on my body were agonizing, however. I couldn't enjoy the ride at all because I was trying to keep myself from vomiting all over the poor people sitting next to me. I managed to keep my stomach intact, but when the ride was over, DH had to hold me up til we got outside. I sat on the sidewalk for 30 minutes fighting dizziness and nausea. After a while I felt well enough to walk around and enjoy the rest of the day. However, later that evening, after a wonderful dinner at Rose & Crown, I got terribly sick again

and spent a long time in the restrooms in America. I felt totally destroyed and beaten up. My head was pounding, my insides felt like I'd been hit by a truck. My poor DH, he thought I'd died in there! He was about to send a random stranger in to look for me.

The next day, I was absolutely fine. But I definitely learned my lesson that day -- M:S is NOT for me!
