Can't Sleep

Recently I've found myself tossing and turning, unable to go to sleep. I've tried cutting back on caffeine during the day (absolute torture), turning the TV and computer off, adjusting the temperature (as much as I can), and yet I still can't seem to get to sleep at a decent hour. We're talking wide awake at 3 in the morning type of can't get to sleep. I've posted a few tales recently during my late nights up but usually find that my writing isn't the best when I'm sleep deprived. What to do? Any tips that you dear readers may have would be greatly appreciated. Now I'm going to go try counting sheep.
