< Advice about breaking YouTube addiction?
Hmm... I'm having a similar problem. What I've tried is clearing my Watch later list, saving everything on playlists, looking for the audio version of some podcasts I like, and downloading the videos to my phone, so I don't have to open the App (YouTube Vanced for Android)
The feature from YouTube that steals more of my attention is the Home Screen, since it recommends you videos to waste time. Some other way is using

to avoid that tracking of preferences.
And finally, I use on my laptop a plugin for Chrome based browsers called DF Tube (Distraction Free), to hide comments, recommended videos and similar distractions, ha =)
