I think you need to figure out why you can't fall asleep. Is it because of too much energy? Then take a benzo like Ativan or Xanax. Is it because of chronic insomnia where you're tired and can't sleep? Then take insomnia medication

I think you see where I'm getting at.

Try talking to your pdoc about why you can't sleep. I think s/he will help you more than I can.
