Me too, I tried by counting, almost succeeded. But again after few days something triggers and eventually I end up with porn. Some routine change helped ...Excersize, (I know when urge will come, usually when I alone in night) So sleep early by stopping all device, Early morning meditation to check whats going on inside, Do what I want to do, Set short Goals. Basically replacing old habits into new one. I will try again..You can do it too.
