Yeah I used to have the same problem, I'm highly susceptible to addiction. In the words of the Lord our God "if your hand causes you to sin, cut it off. If your eye sees sinful things, pluck it out. It is better to be without a hand, or live blindly than to sin." The best solution is drastic action which involves just cutting off your internet access, praying about it, and getting support from trusted friends. You can make it through it, after two weeks you won't have the urges anymore.
