I'd recommend going non-stop all day, doing something every second. Be up at 7 or 8 and sit or lay down as little as possible. Then be ready for bed by 10 ish without watching TV or being on the Oz an hour prior to this. Cut caffiene and sugar too, I went through a phase like this, would be up at 4am for work and wouldn't be able to fall asleep till 1:30am the next day, giving me 2.5 hours of sleep a night, regardless of how exhausted I was. Then I stopped vegging out watching television and kept myself busy throughout the day, then again, everyone's different. Best of luck with the snoozing.
