Suggestions for making long Air Travel more comfortable?

Hey all,

I'm going to be flying to South America in a few months (about 14-15 hour flight). I've been on a plane numerous times, but most have been short flights. The longest i have been on was a 6 hour flight to New York.

I get really stir crazy when I'm sitting in my seat for too long and I'm worried that this flight will be quite painful in that respect. I also get nauseous in turbulence, but it's not too bad. I can only sit and watch movies/listen to my iPod for so long, and I have trouble falling asleep on planes.

Does anyone have any suggestions that would make this trip more comfortable??? I have considered getting prescriptions for Valium, but would rather get something over-the-counter for ease of purchase and easy transport (without paperwork). Or if anyone else has any non-drug suggestions, though I'm not sure new headphones or a pillow are going to solve my problem.

Thanks in advance!

I know what you feel like. I don't like sitting long on planes but what I do on long plane rides is bring an ipod or dvd player. Once I get bored of that I usually try to bring a book, Magazine, or some quiet games such as word searches. Another thing you could do is try to talk to the person next to you to see if you have anything in common. Good luck and have a good trip!
