Try this, exercise 2: http://www.drweil.com/drw/u/ART00521...exercises.html
I had some success with it, even though i didn't stick with it.
I've had insomnia since i was about 10yo, and have tried everything (including stillnox, which made me hallucinate for 6 hours! Never again!). And honestly the only thing that worked was drastically reducing my sugar intake. I have no more than 6-8 teaspoons of sugar per day (which is the amount reccomended by WHO), and now i fall asleep within 20 mins and stay asleep all night. The difference is amazing.
Good luck, sending some zzzzzz's your way
