Dont sit around for too long. Keep your mind interested in things you enjoy. Don't consume too many sugar foods. Eventually your body is just going to crash no matter how much sugar you consume. Try natural energy boosters like vitamin c. Keep on plenty of lights to help trick your body into thinking its still daylight out.
Coffee or other caffeinated beverages or caffeine pills [that can be purchased over the counter]...If all else fails, you could always smoke a bit of crystal meth!! then you'll be awake for a week straight rather than just one night!! (LOL!!! Sorry, I'm joking, LOL! It certainly wouldn't be wise to go that route, but it popped in my head and I jus had to throw it in there! LOL!)
