If you're looking to put the brakes on that, I've used LeechBlock to add a 5-second timer to opening a new HN window (along with other block schedules). The timer even fails if it loses focus, so it really helps slow you down.
echo '127.0.0.1 news.ycombinator.com' | sudo tee -a /etc/hosts
You'll still open new tabs and go to HN, but you'll be reminded quickly, and every day can be downtime day \o/ (for you, personally)
It's like they say: "Your demons will comfort you when no one else will. That's why it's so hard to get rid of them"
youd go through that effort when you could have just stopped though.
If I could snap my fingers and break toxic habits and patterns, I would have done so decades ago :)
