An essential reason that prevents you from falling asleep are thoughts that appear in you and that you follow.

No matter what they are, you should be aware of them while you fall asleep, but do not respond to them (and do not fight them).

Instead, they can be abandoned and abandoned with the phrase: "What happened had to happen, how it happened" with respect to the past and adjusted according to the present and future.

A good way to not be distracted by anything is to try to get as close as possible to the imagined end of the universe when you breathe in, and to stay in this position as you breathe out.

The next time you breathe in, you try to get a little closer to the end and stay on this point as you breathe out.

You repeat this over and over again - especially when thoughts come to your head again.

(Since the universe is infinite, there is of course no end to it).

The more often you do this when you fall asleep, the better.
