Any pilot that hasn't gotten quesy at the least during their training is a liar. I'd say there's a 50/50 shot that you've lost it once or more. I did once myself.

Besides the point, picking when you fly in relation to the conditions does make a huge difference. Picking an early morning flight is usually the nicest, calmest conditions on average. Having an instructor that doesn't do what you meantioned is another bonus. Someone responsible for your well-being is a huge plus. If you decide to continue, good luck, and it does get better as time passes
