What about motion sickness? I get sea-sick. Will I get air-sick?

Sure you will.

Don't worry though, they have a throw-up bag in front of you. This is because a lot of people get air-sick. Don't stress about it, you are going to feel really sick, start feeling dizzy, possibly a little faint. You will feel like throwing up and reach for the bag, then think "ahh no I am okay". But then you will feel like throwing up again, you will reach for the bag, and barf all over the inside of the bag, but most probably also miss and have some fall on your lap, on the cabin floor, maybe even on the person next to you. They just don't make the bags big enough. The person next to you will be pissed at you too, so choose carefully where you sit.

So as I mentioned, don't stress out about it. Just throw up in the bag and everything is okay. People around you are going to hate you though, and no matter how nice they are PRETENDING to be when you say "oh I am so sorry" and they say "that's okay it happens to the best of us" - they are lying. They hate you. They want you to move seats. You stink. You just threw up all over yourself.
