I used to have sleepless night once in a while generally due to over-thinking while lying on the bed for years till 2014/15. I experimented with meditation before sleep and since then I haven't had a single sleepless night in all these years. The practice is simple. Turn lights off. Sit (with hips on the pillow) on the same bed you're going to sleep. Sit straight and comfortably (preferably in cross-legged pose), gently close your eyes. Now concentrate on the area Right in the middle of your chest. You can feel bone, muscle or anything else when you focus here. Just continue to concentrate on that physical sensation you're experiencing. Just discard every thought that comes even the thought of how much time has passed. If mind drifts onto some thought, gently bring it back to the area and its sensations. About 8 to 10 minutes of this meditation and you're ready to sleep. Lie down, keep the focus on the same middle of the chest area and don't entertain any thought. They'll still come and if you focus on them, start analyzing/thinking about them, you'll lose the peaceful state just gained with meditation. And you may have to do it again

I generally fall asleep within first few minutes of lying down after this meditation.

The above is my personally tested and daily practiced method. You can also try Yoga Nidra guided meditation audio which has helped people in relaxing the mind before sleep. Go here http://www.swamij.com/Meditations.htm
