Find out if your addiction is because you find the world boring, or if you're trying to escape from something you fear.
If it's the former, block the addictive content and replace it with other things you find fun (hobbies, books, movies, etc), paying attention to how it's more worthwhile to do so.
If it's the latter, find out how to overcome such fear / anxiety and to stop using addictive content as a crutch.
100% agree. I happened to do this this morning as I was dealing internally with another, somewhat similar, sort of addiction.
Earlier in my life, I was addicted because I was fearful/anxious/traumatized. It was a (shitty, yet effective) escape.
Now that my life has been stable for a few years the addiction came back up. I wondered why, and I realized it was because I was bored. It made things more challenging (which was a motivation to quit I thought), but it turns out the challenges introduced by this addiction actually make my mundane day-to-day more stimulating.
