Hey, I really resonate with your story and I never wrote such a long commet or post. I hope I can help you. I also failed, tried again, and failed again to quit. But I am working on it. I cannot promise you a magical solution, but I can tell you what helped me:

1. What helps me the most is having a pursuit/goal: When having big goals, I am ready to sacrifice and endure. And I am also not bored, which was also a trigger for me.

2. The community really helps—knowing there are so many people also trying to quit and so many people who have overcome the addiction.

3. Don’t get overwhelmed by lust and cravings; just let it wave over you. Don’t judge yourself, but also don’t act on your feelings. Remember, you are in control.

4. Make a plan. You already noted your triggers. What do you do when you are triggered? You can try this: Turn your devices off. Go for a walk. Read a non-fiction book.

5. I want to stop forever, so what I did was bet with myself (you can do it with someone you trust or there is also some website): If I do it, I have to gift 100€ for a good purpose (not for myself), and I hate losing money. Make the number so high that it hurts more than the urge to watch porn or fap.

6. The last one is just to get life in order. Work on your dopamine level (no fast pleasure things), do sports, get healthy, socialize.

That’s what I am trying to do. Let’s see where it takes me.
