I can stop anytime...can't I?

Do you fear that life without the Internet would be boring, empty, or joyless? Do you lose sleep due to being online late at night? I was about to log off for the evening, but wait - I must post this:

"Dr. Grohol's Psych Central - Internet Addiction Quiz."

Where did Dr. Grohol get this? Am I the last person to discover it? It looks like an "Are you a problem drinker?" quiz, modified for compulsive Web surfers.

Don't ask for my score. I'm in denial. I question its validity, anyway...did they control for blogging?
