Thread like these remind me how weird I am. I get up and go to bed basically the same time every day so that I'm not fighting (effectively) jet lag between weekdays and weekends. At the end of the day I get into bed, turn out the lights room, and do about 20-40 minutes of scrolling (no blue light filter). Then I set my phone (which is on DnD automatically) on the charger, feeling like I've caught up with the world and go to sleep.

I started the "same time every day" schedule in my mid-20s when I was having problems getting up for a job that was earlier than I was used to. I read about jet lag effects and Seasonal Affective Disorder (variable diurnal cycles/short winter days) and got a sunrise simulator to even out my day - or at least my mornings. It seems boring, but in a lot of ways it's freeing not to worry about being too tired or not being able to get to sleep. [admission: I have a mentally tiring job, so my brain is ready to switch off at the end of the day, which helps]

Yes, the no phone in bed rule is a good one. I also try not to look at my phone first thing in the morning aside from turning off my alarm. Then I get up and start my day before checking the phone. Don't let your phone dictate your day, start it yourself with intention first.
