I don't know if this qualifies, but at Six Flags I got centrifuged around so damn hard on a torture device/ride called "The Tomahawk" that I'd swear my stomach was sticking out of my left ear. Afterwards I had to lay down in the parking lot for about 45 minutes before I could stop puking long enough for my friends to move me in their car, I literally would have had them call me an ambulance but I knew that the ride to the hospital would have probably killed me. And then it took over two days for me to get back to normal again, so Needless to say I don't do amusement parks anymore.
And for the record, no I hadn't been drinking!
