Being nervous the first time, the "butterflies" will also contribute to being airsick. I never get airsick as a pilot, but there's been a few times in the back where I almost lost it. Once was just on a 3 hr gnd delay with just the apu ventilating an entire 757. It was so hot, I really started to get the burps. We are in March-April, the windy months. Summer, there will be a lot of convective turbulence, but you'll get used to it. I guess the question is, what are your goals? PPL? or more? The one thing that people rarely ask about is all the tests. You are tested continuously in this career, you have to get over test anxiety and you have to constantly study to keep current.
