You're not competing with us, we're struggling right here beside you. We're one team, and we want to see you succeed.
How have you entered this? Have you really sat down and made a game plan for how you're going to beat it? If not, I can personally say that's what made the difference this time I quit.
My advice, take it or leave it:
Stay active in this community. Update your journal. Find a few people you click with, check in on them, give them kudos on their progress, etc. Community helps a bunch.
If you know someone in real life that you can confide in, and share your goals with, someone you trust, then you'll have someone to be held accountable to. But if you're not ready, or there's no one you trust, then maybe not. If you don't have a therapist already, you may be able to find one your insurance covers, or free therapy. There are also anonymous groups for addicts, you may have some near you.
Find the positive habit you're going to use to fill the void left by your bad habit. Preferably something exercise related (dopamine hit, feeling good about progress, etc all really help). Make this a realistic and concrete goal. "I'm going to run more." is a bad way to set a goal. "I'm going to always have clean running clothes in my room. I'm going to put on the running clothes and walk/jog/run for 30 minutes, at least 3 times a week." Is better. "I'm going to run 5 miles every morning before work." Is unrealistic. Remember, the best workout plan is the one you'll actually do.
Change your settings, break your automatic habits. My therapist suggested moving my furniture around, but what I ended up doing was moving my standing desk higher. I had a very strong habit of sitting in my chair, beginning to touch myself, and since I was already on the internet... But now it all feels unfamiliar, and just doesn't happen on its own anymore.

I don't know how you do with dry, scientific articles, but this one is good. It goes into what porn does to our brains. TL;DR, it literally makes you less human and more animal. I found it fascinating, but it also enraged me. This giant industry has not only exploited its consumers into addiction, but is literally turning them into animals.
Another read that helped me was the book Dopamine Nation by Anna Lembke. It goes into several types of addiction, but keeps bringing it back to our brains.
Finally, forgive yourself. We all have backslides. I quit smoking, IDK, 5 or 6 times before I was finally done for good. I tried to quit or cut back on PMO quite a few times before I even admitted I was addicted. And this is my 3rd or 4th attempt since then.
But don't let forgiving yourself turn into permission to do it again. There's a fine line between beating yourself up, and enabling yourself. Walk it.
You got this! I believe in you!
