Ambien is good. Most people only need 5mg, but they do make them in 10's.
AmbienCR is woefully inadequate. Restoril works too, but depending on how big a person you are, and probably your metabolism, so you may have to play with the dosage for a week or so. They come in 7.5's, something else, and 22.5's. Also, Lunesta isn't terrible, either. It comes in 1, 2 & 3 sizes. I found 3's to work best.
Do not let them give you Tranzdone (bet I spelled that wrong). You'll feel groggy for a week. Yuck.
Can you tell I have a bit of a sleeping problem myself? Sigh.
Non-drug wise, I find it useful to lay off the caffeine after 1pm. I also find it useful to do something physical every day, even if it's just cutting the grass. Sometimes I lay down and count each breath, in and out. I made it to 786 once, but most of the time it helps. Also it helps to tell your brain that your body parts are relaxing, one by one. You start at your toes and tell yourself, "My toes are relaxing, my toes are relaxing, my toes are relaxed." And so on.
The other thing that sometimes helps is listening for things from outside. We get trains going by some distance away, cars hiss by my window (thank you Jim Morrison). just try to get "outside" using your ears as much as possible.
Also some people have had success with "white noise" such as a thunderstorm, birds, seashore sounds, oh, there are lots of them.
Last point....I promise. If nothing works, then I just get up and start doing something instead of dwelling on not sleeping. Clean something. Wash dishes. Dust. Usually just the thought of housework will put me right back to sleep, but if it doesn't, I try to remember than nobody ever died from losing one night's sleep and since I'll probably be tired from not sleeping much the night before, I just reason that I'll be tired enough to sleep well the following night.
