The only time I physically got sick was the morning before each checkride (ppl/inst). Got close first time in IMC, and in an intro to dogfighting.

Just keep riding that horse and it'll get better.

Just curious, do you know what the winds were on the day of your discovery flight? If you know the date/time and the airport, we might be able to look at some historical weather data to figure it out. I'm asking because what's turbulent to a newbie may be "par for the course" for the instructor.

Good luck and let us know how it goes.
