Hello and שלום עליכם!
Good first step. The more you post, the more clear you will become in your own mind how important this is to you. I wanted to stop many times just like you. I tried to stop just like you. It worked for some time; but then I would forget how Harmful this is to my life and relationship to hashem, I would lose my focus and fall when lust hit my door (like its doing now). Since I joined this group and try to read and post on the forms, stopping this behavior has become the most important thing on my mind now. I am always on guard. How long will this help?? I don't know. But every day I score a point. A point that will stay on my record forever. And that's what matters.
Good luck on your journey, brother!
