I have the hots for the Mother something chronic.(except the Gilmore Girls...that show is just too girly for me...)
As for rollercoasters, never go on 'em so can't answer the question. I have been on all sorts of planes, trains , boats and automobiles though and have never had a motion sickness problem. The closest I came was having to wear a helmet to block my vision while learning to fly with just instruments (did you have to do that Keith?), I could only handle that for a little while at a time before starting to feel nauseous.
