try restricting your browser to not access any porn content. at least that helps one in this fight. i tried it and whenever i try to go back in the process of unblocking i find myself asking if this is what i really want. all it takes is that one moment of questioning yourself.
Its hard when you look at it as a whole 21 days so divide it in parts.. do 2 days at a time but consequtively. trust me am at day 4 and i already can fell the change. i am more motivated than ever. its better to push yourself than punish yourself. yeah... keep going and whenever it feels like you wanna give in... just find one person in here who is also struggling and encourage them... it changes the mood completely. i was almost giving in before deciding to reply to you and now as i am finishing this text.... man i feel the loath i have for porn and i don't wanna even see it..
