I will sometimes drink chamomile and/or hops flower tea before bed. Hydrates me, tastes good and I'm out like a light. I backback to hike not camp - and often I don't sleep well. I will also sometimes take a Tylenol PM (1 pill, not the full 2 pill dose) if I'm achy.

I don't see how it is "cheating" though. My husband suffers from insomnia and it is pretty serious stuff.
