I only read this article, Are gadgets, and the Internet, actually addictive? a week after it was published but I can totally relate the the Internet withdrawal. I get that! I was just saying to Richard a couple of weeks ago that I am spending so much time online now because of the internet deprivation I experienced for the past 11 months when Aaron didn't sleep longer than 20-30 mins at a stretch in the day time. I seemed to have accumulated some internet debt and I'm forced to repay it now by spending all my available time online.
Luckily I don't have a Blackberry otherwise I'll have what they're calling Crackberry Addiction too!
