It's a point of pride for me that I didn't need the barf bag. Which is weird, because I get seasick so easily I managed to get seasick on an aircraft carrier. But even violent aerobatics don't bother me at all.
Closest I ever came was getting a "check ride" in the backseat of an F-15 because I was our unit's "Airman of the Month." I didn't quite piss myself, but I was a bit wobbly in the knees walking away from it.
