That works wonders for me. You won't fall asleep in less than two minutes the first time you do it, but after doing it for two weeks, you will.
Relaxing the muscles is very important to be able to fall asleep. Pay attention to the facial muscles and those of the eyes. To clear my mind of distracying thoughts I count from 120 to 0. These days I seldom reach 100 before I'm asleep.
You might be skeptical that the process works as stated in the article, as I was, but after you see that the process works reliably you also get the benefit of less anxiety about being able to fall asleep.
It is also very important to check your 25-OH Vit D serum levels. Watch the interview with Dr. Stasha Gominak about the relation between vit D and sleep that was posted recently.
