That's what we call it still right, I'm not old, right? Anyway I'm horribly addicted to ragebait on reddit and despite being permabanned sitewide (can't even make new accounts) I still keep going back to it. It's obviously depressing and angering. It's not fun!
Have a trigger to make sure evertrimrbyou have an urge to go on there you do not. Pinch your arm or smth. Put it in a folder on the last page of your phone and the few extra taps and swipes will be enough to remind you or trigger your memory not to do it.
Yup, and if you find that it's still not enough then you can add more friction.
For example, if there is a certain subreddit that you go to a lot and don't want to, block that subreddit at the browser level.
You could block the entire website, but you don't want to get into the habit of unblocking things (ex. If you need to access a post with some resource, after coming across it when searching). Better to block what you need to block, instead of overdoing it.
