I can also offer this advice, as someone who uses Facebook (mainly Marketplace and groups) but is not used by Facebook: limit the number of your Facebook friends to the absolute minimum you can, people who you don't talk to or talk to elsewhere, remove. And also unfollow everyone in your news feed. This will make the news feed show you content only from pages and groups (and possibly a handful of people you actually want to see content from). I never struggled with Facebook addiction, Facebook is so nasty I couldn't even get into it to begin with, but it has some utility which I like to take advantage of so I keep my account around gutted in this way which is so utilitarian and unexciting at this point I don't think I could even get addicted to Facebook if I tried.
