P.S. I took most of this from a drug addiction website and changed drugs to internet (same theory right?)Well, I thought it was funny.
My real answer is that everything comes down to choice. I think addiction is a farce. Regardless of how much you WANT to do something you still have to CHOSE to do it. I refuse to believe that people are helpless against their choices so therefore there is no such thing as addiciton. There are only poor choices.
