I’d like to know if you guys have any methods to sleep fastly.

I like to listen to some meditation or hipnosis. They help me to free my mind from problems and worries and concentrate in what they say.
Doing yoga also helps (in the evening).

I like to visualize my happy place, like on the beach of the ocean, and focus on my breathing. There are apps you can buy that have sounds you can listen to while falling asleep, I’d try that too.
