if your on a plane that long, they should have movies, i mean most airplanes now come with a tv on the back of the seat in front of you so you can watch a few movies and that should take up some of the time, besides that sleep and you got most of the time gone
I wouldn't do the sleeping pills thing, if there were some sort of emergency it could be dangerous. Maybe nyquil or something(I can take a double dose of nyquil and have cool lucid dreams and wake up when needed.)
I actually need to stay awake on the plane because i need to get over my jet lagg asap. It will be 7 pm in hong kong when i get in, but it will be 2 am where i am. Soooo i'm probobly going to be getting to sleep around 4 am Pacific time... At least it will fix my sleeping time a bit.
Raziel said it was for Gameboy Advance SP. DS does not come out for another couple of weeks if I am not mistaken. You may be able to pick one up in Hong Kong though .
DS comes out on November 21st in America, and sometime in December in Japan.
