I've installed the k9 web filter to block all porn sites. I've started to go to the gym 3 days a week, and try my best to do 1hr cardio on the days im not at the gym. But everytime I browse a while on You tube, i relapse because you can get away with a lot of things on youtube. So i just MO twice today after 2-day streak. Why arent the things im doing now not helping me, or what can i do to further prevent urges?
