Speaking of being sick, I was profoundly sick the first few times before I went solo. Wasn't fun but your body gets used to it. Coming up to 20 years and a few thousand hours under the belt and nothing since. Well apart from being sick in the back of a DC-3 on a severe turb day after a full night on the cans capped off by a dodgy kebab!
I think Chuck Yeager mentioned he was crook the first few times as well.
