try working out before dinner or after dinner (light work out)

reading books just before sleep

no wine before sleep. it makes your heart rate faster

most importantly, relax when you are sleeping. you cant sleep when there's so much thing going on in your head. clear your mind first / stop thinking then sleep.

try this method when you are at the bed trying to doze off. breath in for 4 seconds, hold 6 seconds, slowly breath out for 6 seconds. repeat until you either doze off or you can feel that you're relaxed
