20 Hour Plane trip
If you have an IPAC or something similar, download some games and that will help pass the time. Most international flights have movies that also help. I like to take some Tylenol PM and and a benedryl to help sinuses and to help sleep. If it's not turbulent, getting up every now and then and walking the aisles helps. I also have an IPOD and I download some nice easy music to listen to that will help me sleep. The planes often will have music for the locale you are going to and I like to listen to that, helps get me in the mood for that country. If you have a book about Singapore, that will be a good time to review that. Remember, don't chew gum in Singapore! Have fun!
