Huh, that's exactly the solution to addiction? Step 1 is always changing your behaviour patterns to break out of habits and avoid things that draw you into it.

Make your bedroom a phone-free zone, charge it in the living room overnight, use the built in parenting and screentime controls that every modern phone OS has, don't let your kids stare at the screen all day. Etc.

This isn't rocket science. Self control is one of the most important things you need to learn. It sucks and it's hard but it's basic life stuff.

The only difference with social media addiction vs drugs/gambling is that it's not socially ostracized like other addictions so people ignore it.

This is the lie that keeps people addicted. Plenty of people quit their very real addictions every day. If you imagine you're helplessly addicted, you will remain addicted.
