Late Night Urge

If have accountability partner, you could have them set a timer on your phone what it turns off your phone until the morning unless you have a passcode. iPhone has a built-in setting of screen time.

I go to sleep earlier

Cadan’s advice is great. I would also add that you remove any devices from your bedroom

Something that has helped for me is to go outside and just enjoy the night sky and ambience. Nighttime for me can be a very calming experience where I can find peace. I don't know if you're religious, but prayer can be helpful too. Or if all that is too much going to bed is always an option lol.
