How do you make sure you won’t turn your phone again this evening after you’ve already unplugged?

I have a bedtime mode set on my phone that turns on the "do not disturb" automatically every night. I also leave my phone in a different room (usually the kitchen) once I am 'unplugged' for the evening.

I make sure that my phone isnt within arms reach of my bed, and that all notification sounds are turned off. This gets rid of any temptation and makes it more of an effort to have to get out of bed and walk across my room in order to look at my phone.
