Keep yourself busy. Watching TV isnt one of them, some think you can watch TV and keep awake, there wrong. Drink black coffee, dont dilute it with milky goodness. DONT put a heater on, Levian recommended it but the heat will just make you even more tired. DO leave your window open, the noise and cold will keep you awake. DONT get tucked up in bed, thats the biggest no-no of them all. Sit on a stool or something.
