I fall asleep super easily, within 5 minutes of trying to go to sleep. I do have anxiety and the like, but it doesn't keep me awake at night usually, just messes with me all day.
Even if I chug a cup of coffee before bed, I can still crash out no problem as long as it's not freezing cold or something. I'm really not sure why it's so easy for me. I don't do anything special or different, other than the fact that I don't take naps during the day (they give me a headache).
