"The Shallows: What the Internet Is Doing to Our Brains" by Nicholas Carr might be of interest to you. And, well, to almost everyone here - your symptoms probably already appeared in one way or another to anyone who's reading this.

Personally, while I consider myself pretty disciplined, I feel deeply frustrated (almost angry at myself) whenever I'm actually trying to focus on something and feel the need to also do/see/check/read something else. Not exactly a facebook feed, but I've come to Hacker News while reading. I don't know what's the most commonly accepted definition of addiction, but this certainly feels like it.
