That's because you need to fill the wound with something else. You can't have a void, you will fall right back into binges on HN. I have since cut my usage way back when I started working in putting and guitar practice into my downtime after work to give me something to improve on outside of work, rather than more scrolling and refreshing that won't mean anything a minute, a week, or 10 years from now, unlike spending that time using my putter every night...
I'm basically trying to turn my life into an RPG and leveling my character up in real life instead. It's kinda disturbing that I have to rely on video game mechanics to self motivate, but maybe that's what happens when you grow up addicted to video games and electronics. Big contrast to my dads generation, who grew up playing baseball and swinging from trees in the woods.
