Take a deep breath first. Ok, now focus on the job at hand. As someone single, I can only try to understand what you're going through. But, lustful thoughts are things that both married and single guys have to deal with. It plagues everyone in some form. I'de suggest to try as much as you can to not focus on being clean for a week, because who's to say what tomorrow will bring? You are only held responsible for now! So focus on the now, and zehu. Will it suddenly be easy? Maybe yes, maybe no, but you gotta try to change what your focus and end goal is. I used to think in terms of getting to the seemingly super elusive and magical 90 day mark, and you know what? It never helped me get there! If anything, it made it worse. Once I started to work (still working on it) on taking it one moment at a time, I now have begun to really see progress. KOP and don't be alone in this struggle, we're all here for you.
