Start doing your homework, it will make you sleepy right away :)
Haha,Bel,I have to say that maybe you can be an editor. once you finish your story.
I would take a cup of brandy
I usually imagine a story in my mind, then If the next day I can't sleep either, I continue with the story, I already have some "chapters"... (=_=) ZZZZ
Sometimes read or listen holyquran and drink water
