I generally fall asleep within first few minutes of lying down after this meditation.
The above is my personally tested and daily practiced method. You can also try Yoga Nidra guided meditation audio which has helped people in relaxing the mind before sleep. Go here http://www.swamij.com/Meditations.htm
I have a lot of pain and am unable to dissociate from it enough to sleep until I’m completely exhausted which several nights a week meant no sleep or just a few hours. These tinctures along with another pain medication (extremely low dose naltrexone, no side effects except better sleep for me) allow me to get a very good nights sleep 80-90% of the time which was a significant improvement in quality of life.
Give it a try if you are having no luck elsewhere!
Additionally, I don't work or talk or message 1 hour before bedtime.
Additionally, I implemented all advice from CBT-I. It took few months to develop a habit, and I'm feeling better every day now.
What has worked well for me is to deliberately focus my mind on simple, pleasant topics instead of negative, annoying ones. That time at work when I solved a difficult problem. Dream vacation plans. The great view at the end of a long hike.
I'm aware this may not be easy (or possible) for everyone to do.
