What do you do when you can't sleep?

Speaking of myself, I have insomnia few times a month, sometimes few times a week (depending on my activity and stress level). It usually lasts about 3hrs, when I'm lying in my bed trying to fall asleep. Despite I'm tired, I just can't. Sometimes even closing my eyes feels uncomfortable.
One year ago I found a solution.
I listen to "The Gateway Experience". It's something like a course of how to have out-of-body experience. It's divided into 45min parts. Here's the most amazing thing: 1.2 part of this course (veeery early begining, only relaxation) makes me fall asleep, usually after 15mins. It always works, no matter how stressed I am. If it works for me, there is a great chance it will work for somebody else. Exact name of that tract is "Wave I Dicscovery: Introduction to focus 10". TGE can be easily found on google, it sometimes appears on P2P's.
Anyone having the insomnia problem: try this and post your comment. It's important to listen to TGE in headphones (paying attention to where's left and right channel!), and to have an absolute silence to focus properly. I advice starting from 1.1, since it's an introduction.

Jam it back in, in the dark.
