Any tips on sleeping better

Music in your ears is better when you are sleeping at night

Did you ever try Melatonin? It is a natural human substance that the body produce in preparation to sleep.

Don't look at mobile/bright devices for 30 minutes to an hour before bed, i recommend just reading books, and when you sleep you can actually position a pillow underneath certain spots to help position your spine which can make you relax more.

ASMR seems to work for me, when I cant fall asleep ASMR head massages and whatnot

Get into a comfortable position then relax all of your extremities. Then just don't think about anything and just relax further.

What works for me is exercising early in the day and continue to be active throughout. But, if all else fails melatonin works pretty well.
