Oddbean new post about login | logout I did this three years ago with my girlfriend. Works very well. Definitely get rid of app installing. Also find things you enjoy doing in real life - that's the best permanent solution.
Exactly the conclusion I am coming to. Do you still have your phone limited?
I transitioned to GrapheneOS on a pixel so while I don't have any limits, I never reinstalled any google apps or things like twitter, Facebook, Instagram, etc. I also use Mullvad VPN and have all the DNS content filters turned on so most social media, gambling, or adult content is unreachable. Ultimately there is always a way around a filter so self control and outdoor hobbies are also very important.
