Quitting porn is not an event, its a process
A few things that really really helped me to quit was
1-Deleting every social media app(i only have youtube on my phone)
2-As brother @AkhiraisReal pointed out Lowering your gaze really helps as well and whenever you find yourself looking at woman in a sexual way Instantly look away and put your hand on your heart and remind yourself that She is just a human just like you not a sexual object
3-Identify your triggers and eliminate them from your life, for example in my case I almost always got the urge on my bed while using my phone so i stopped taking my phone to bed and putting near me when i sleep(it really helped me)
4-Stop counting down the days, it doesn't work and it will frustrate you instead record your wins everyday and be happy that you won the battle of the day
5-Dont Give up if you relapse, instead look at what made you do it and eliminate that frm your life, I myself failed a few times but got back up and now I'm here
6- Get an accountability partner that helps you in your journey
While I'm not fully recovered yet I can definitely feel the benefits of not watching porn, my goal is going 2 years without pmo
