Ginger Pills...
They work, believe it or not.
I tried them on my flight yesterday and for the first time, I had not even a hint of Nausea, no matter what maneuver I tried.
Yesterdays flight was perfect. 7 touch and goes and Islip/MacArthur, dodging 737's all the way, then it was back to class D airspace at Republic. (Which, oddly enough was much busier than the class C I just left.)
The sun was setting behind the manhatten skyline, and for 10 minutes, as I flew west toward home, everything was perfect with the world.
As for the ginger pills, I'm pretty sure that was what did the trick, though it could also be that I am getting quite used the the motion of my aircraft.
