This is the only thing that worked for me as well. Installing browser extensions and distraction-blocking apps helps for a couple days, but ultimately I'd start cheating and would uninstall them.

Leaving my phone on the charger in the bedroom after 5pm completely removes the temptation. If somebody needs to reach me, they can call my wife or just leave a message for me to check in the morning. I've been doing this for several months and it's worked wonders for my attention span, my sleeping habits and my vision.
