Read up on “executive dysfunction”, I’ve got this too and many evenings end up watching youtube even when I wanted to play a game.

One thing helps with this with 100% success: multiplayer. When my buddies are online and ask to play something, I’ll immediately close youtube every time without issues, no matter how interesting the video is. Sometimes we don’t even play anything and just chat, but even that seems healthier than watching youtube alone.

I know it’s easier said than done (getting gaming buddies), and doesn’t usually cover breakfast time, but it might help if you tried that.
