David Goggins talks about back stops in one of his book - that gave me an idea to see if I could go further than having a reminder go off everyday to push me to go to sleep (wasn't really working for me - too easy to hit ignore)
I created a Bixby routine that is working for me - screenshot attached.
The routine set to run at times between what I like to call "my weakness hours" If i open any of those apps (Social media, Youtube, netflix, Ubereats, etc) - it plays an audio reminder and opens the camera to selfies mode - a personal message I set and it plays while I am effectively looking in a mirror. This has helped me get off the couch and to bed and I have even lost a fee pounds because I'm not snacking late at night.
