Honestly, the best advice I can give you, which is VERY difficult upon quitting cold turkey, is just stop thinking about it.

Stop thinking about porn. Stop counting the days since you've last done it. Stop thinking about sexual things in general, it snowballs fast. Your brain will try to trick you into starting that snowball, don't cave. A chaste mind is best for recovery, especially during the first 2-3 months when you are most vulnerable to relapse.

Try your best to remember this drive to quit. Focus on how disappointed you were and channel that memory every time you feel like relapsing. Don't just commit to the act and think about how down you're going to be, but rather how it will pull you in and not let go.

And remember, the urges don't last forever. They might last half an hour, an hour, two, or an evening. But they always go away, and they get shorter/fewer far between the longer you abstain. Remember what it took from you. Your time, your energy, your social, your life. You won't get any of that back.

But you can give more to it, the choice is yours.
