CityVille addiction: A friend's cry for help (For Real...thanks for helping)

A normally Hyper-Rational friend writes:

"I think I may need Cityville therapy.  

I don't know how it happened.  

I was on Facebook minding my own business.  

I have never done anything like this before.  

But I think I need medication.  

I simply can't stop.  

And I am ashamed to admit they have my credit card information.  

What do I do?  I may need an intervention."

First, know any resources for breaking internet-gaming-facebook addiction beyond this:

Second, any indication that this is a common malady?

Seems like a Wired article anyway...or a foundation waiting to happen...
