There is a lot of good advice in this thread and I strongly recommend trying that advice before trying what works for me.

BUT, I had trouble getting to sleep my whole life and for about the last 7 years I've been able to get to sleep in much more normal timeframe. After trying most of the other things in this thread (cutting caffeine definitely helped). Two things that have seemed to really work for me:

I have a 7" tablet on my bed and I put on the SAME EPISODE of the SAME tv show each night (currently Psych S4 E1 - though it does change occasionally). I keep the volume low enough to not really hear unless I'm trying to listen to it and the brightness at almost the lowest setting. This is contrary to most advice on the subject and I write it here not to recommend it as a first choice. It is however what seems to work for me when other things didn't. The goal with the content is something that the plot doesn't matter and that you know like the back of your hand so it won't keep you awake to find out what happens BUT it's enough stimulus to pull your attention from your anxieties.

I added a ton of pillows to my bed (11 total). I put 3 on top of my body like a weighted blanket and have pillows to hug on either side of me. I can change to several different sleeping positions without significant pillow re-arrangement.
