I do now, but I used to lay in bed for multiple hours most nights before being able to fall asleep. Here’s a list of things I do that I think help:

• get exercise during the day
• mostly avoid caffeine and alcohol
• avoid spending time in my bedroom other than for sleep
• take 0.5mg melatonin half an hour before bed
• only take naps occasionally and not as a regular habit
• sleeping mask + earbuds playing white noise + specific pillow arrangement that keeps my head in one place, basically a whole set of stimuli that is specific to sleeping
• eat breakfast in the morning
