I can't abandon it...

Probably the biggest thing that keeps me from being sober is how attached I've grown to porn. I have this subreddit that I always go to when I feel like consuming porn. It's the curiosity, the thought of what new stuff was posted on it that I haven't seen yet that motivates me to consume porn. The thought of never going on that subreddit again makes me upset. "What if someone posted something good and I'm never going to see it", that thought makes me procrastinate hard about giving in to my urges. What do you think is the best method to deal with this?
