I've had sleeping trouble for years. I don't get to bed until around 2:00am and wake up serveral times each night.
The only things that helped me are prescription sleeping pills (most are short term because they are addict forming) or smoking just a little pot before bed.
Alot of sleeping pills actually share the same effects as anxiety pills. You're irratibility would be significantly lowered. You'd probably have really realistic dreams, and remember everything from them, but they're tend to be really weird.
If that doesn't work for you, then try reading a book. Might help you get to sleep, but won't keep you sleeping.
