I've had this problem too. Especially lately. All the years I worked in NY I had to be up by at least 6:30am. NOW, I wake up every morning at 6:30 am. Bother!

My grandmother from Italy used to have a glass (small) of wine every night. I find I sleep well with a glass of wine. I still wake up at 6:30am but I usually get a good nights sleep.

In college I did a paper in Comp Class about falling asleep. Here it is in a nutshell.

Lay on you bed in the most comfortable position for you. Talk to your body. Talk to each extremity and relax each one as you talk to it. You can actually feel that part relax. For instance: "Feet relax", (feel them relax), "calves relax" (feel them relax). etc. By the time you get to your head, you should be asleep. Two things are accomplished with this excercize. One, you relax your body. Two, it takes your mind off of not being able to sleep or anything else you might be worried about.

Now, I have become so disciplined I just tell my whole body to relax and it works. I can actually feel each piece of my body relax. I hope this works for you.
