On another topic, unless you have lost your lunch flying or are an IP (or otherwise salty dog), we don't care what advice you have. If you haven't been there or seen it, STFU. I have just been given advice by way too many people who have no fucking clue what it feels like to be completely sick in the plane. "I was passively sick this one time" doesn't cut it....
Amen to that. As another dude who puked heavily through FAMs and PAs (and then at least once in every other stage), I can tell you that if you talk to 20 people, you'll get 20 different answers, but here's what got me through VTs:
I ate noodles (Ramen or similar) about an hour before wheels-up. That way I had a full stomach, but with food that was pretty easily digested.
I also took ginger pills (you can buy them at any GNC or similar). I don't know if they actually did anything, but it made me feel better I guess.
Finally, the reason that I avoided the air-sickness NPQ is that I never incompleted a flight for it. Puke if you have to, get back on the controls when you can, and then push. If you show that you are willing to stick with it, your squadron will probably be willing to work with you.
Oh yeah, one more thing: Quart-size Ziploc freezer baggies. They're easily resealable and have plenty of capacity for whatever comes up during your flight. The freezer bags are also quite a bit more durable. I can't stress enough that they MUST be ZIPLOC! Don't go cheap here or you'll regret it. I still carry two or three in my thigh pocket on every flight. Mostly for dudes in the back now.
