I remember once, somebody told me that "often times when you think you're not asleep you actually are". Though it sounds absurd, this single line has helped my sleep immeasurably because often my sleeplessness is compounded by the frustration of not being able to sleep! So I just lie there, and let me thoughts go where they will and treat it as a kind of wakeful "dreaming". The idea being that even though I'm "conscious" of not being asleep my body is still getting the benefit of rest. It doesn't help completely all the time but it certainly takes the edge off.
