I have been on probably over a hundred flights, many on small planes (the ones most subject to turbulence) and have never seen anyone get s*, nor have I ever gotten s* on a flight (although coming back to NY from my cousin's wedding this summer we flew through the remnants of a hurricane on a small plane and I thought I might get s* then because it felt like a roller coaster and I was terrified the plane might crash--which has never happened before or since). There was one time this past Christmas when I saw a flight attendant steam cleaning a seat, with no indication if anything happened, but that's all. I always take dramamine which makes me sleepy, but doesn't knock me out.

I took my first transatlantic flight this past November to London (5 hours there, 7 and a half back) and nothing happened. For long flights I take phenergan which is an antiemetic but also knocks you out, which is nice.

Another thing that can help with motion sickness is to keep your window open and look out at the horizon, which gives you an indication of movement if you hit turbulence. The other positive is that you can see clouds coming, which usually indicate turbulence, so you're prepared for it.
