I can relate. I've made some changes in my life that helped avoid Youtube.

The single most effective thing I did was during my week off when I put my phone in a drawer and mostly stuck to my apple watch for notifications and a keycard for my car.

Obviously I need my phone for work, so I've been trying other things to reduce its importance in my life.

I moved the TV from the room with the sofas to the room with chairs. I wind up spending more time in conversation with my wife or my friends on those sofas, rather than "Hey check out this video I saw..".

I've also replaced my phone with my watch for stuff involving unlocking car, and using a mostly-offline Linux handheld device with custom apps to replace stuff on my phone. You'd be surprised how many things don't require internet access; books and videos can be cached, and other things (paying credit cards, etc..) can be done on a desktop.
