RE: Motion sickness?
On eating, I am a private pilot. If I go up on an empty stomach and its a bumpy day or I do a lot of playing around I get a bit of motion sickness, have not thrown up yet though. If I eat, usually something like a salad and a sandwich, I am perfectly fine.
Given your condition, I think the moto: better living thru chemistry. You can't hunt the same day you land anyway, right? So any effects beyond the flight are not a big deal, by the next morning you should be fine.
