Rember that the word "addiction" gets thrown around way, way too easily. Being addicted to something means, to me, that there is a physical dependence on that something in order to function normally in society.
Hell, it sounds to me that you don't have a porn problem, you have a "I spend way the fuck too much time on the internet" problem. Perhaps try to cut back on your computer use completely! Take up a new hobby, make a goal of only looking at the internet for a certian amount of time, leave your laptop at work more. Expand your horizons
