I don't think it's necessarily a bad idea to stay up the night before, but I think it would be better to cognitively restructure your thoughts to get to the root of the problem. Read these boards for some solutions and see what works best for you. I really don't like the idea of purposely jacking with your sleep without getting to the cause of your sleep problems--your thoughts. Probably if you want sleep properly I think you should go for Derma Sleep Patch to be applied on specified body part. It is drug free.
All the best.
