Internet addiction is very real. It's not even hard to fall into. People get addicted to connectivity, the ability to get information and communicate instantly. I know people personally who nearly go into convulsions if the first thing they do when they get home is to get online and check their e-mail.

Anecdotal evidence aside, there have been some studies done about internet addiction. You should check out scholarly journals, I'm sure you'll find something. I did a term paper on it a few years back and if I can find my sources I will post links here.
