Eh, in my limited experience with 'em, 'snot good.
This happened to me as I rode in my first true thrill ride, and then two more other coasters, consecutively, within the span of 15 minutes.
I was twitching and beyond queasy, I had to find the nearest bench and repose, else I would've spun around flightlessly, then collapsed. I stayed there for a good 20 minutes, and it was perhaps the better part of my stay at the park that day, other than the first half of the daydreaming session, where my head was throbbing and it felt as though stuff wanted to erupt from my nose.
I see no need for me to ride another coaster again, though a zipline/cable car would be grand.
