Hi bikash, I am a 69 year old male in the USA. I started having sleep problems about 40 years ago. It has continued for many years. I also tried all sorts of medications, yoga, and other things, with limited success.
If there was a method which guaranteed good sleep–a certain medication or whatever–you would see people lined up for miles/kilometers, waiting to get it. Unfortunately there isn’t.
This does not mean that all is hopeless. I encourage you to stay with this website.
You write that “I can’t fall asleep properly.” But I don’t think sleep is something we can acquire by doing it “properly” or working harder at it or getting more skilled at it.
To learn a new skill, like learning a musical instrument or how to build a house or repair a computer, we have to learn specific tasks, and then practice them repeatedly. Working hard, devoting our time, not giving up when things are difficult to learn will help us succeed in learning this new skill.
But sleep is not like this. It is more like a natural condition which simply comes to us. I think we have trouble with sleep when we try to grab it and keep it and dominate it, almost like trying to grab the wind.
This might sound weird, but I also have dealt with insomnia for a long time. And I am convinced that working harder is not the answer. Again, I encourage you to stay with this website. Martin will not give you a magic formula because there isn’t one, but he has good advice on changing our perceptions about sleep.
