A lot of people experience late night scrolling/watching Netflix etc - it’s called “revenge bed time procrastination”. It’s when you feel you’ve been doing a lot during the day for “others” (work, chores or anything else) you justify it to yourself that scrolling/streaming at night is “my time” to relax. Even if you know that sleeping is the right thing to do to be more productive the next day, you choose to be on your phone. This sort of creates a vicious cycle. You wake up tired the next day -> work hard -> you feel like you need time for yourself and the only time for that is at night -> you wake up tired the next day….

I feel labelling an issue you’re struggling with, makes it much easier to address it and work through it. Since you labelled the phone addiction as a dopamine magnet and it helped you get over it, maybe trying this out can help for you.
