Internet Addiction, are you addicted?

Dr. Young (1996) developed a brief eight-item questionnaire which modified criteria for pathological gambling to provide a screening instrument for addictive Internet use:
1.    Do you feel preoccupied with the Internet (think about previous on-line activity or anticipate next on-line session)?
2.    Do you feel the need to use the Internet with increasing amounts of time in order to achieve satisfaction?
3.    Have you repeatedly made unsuccessful efforts to control, cut back, or stop Internet use?
4.    Do you feel restless, moody, depressed, or irritable when attempting to cut down or stop
Internet use?
5.    Do you stay on-line longer than originally intended?
6.    Have you jeopardized or risked the loss of significant relationship, job, educational or
career opportunity because of the Internet?
7.    Have you lied to family members, therapist, or others to conceal the extent of
involvement with the Internet?
8.    Do you uses the Internet as a way of escaping from problems or of relieving a dysphoric
mood (e.g., feelings of helplessness, guilt, anxiety, depression)?
Patients were considered "addicted" when answering "yes" to five (or more) of the questions and when their behavior could not be better accounted for by a Manic Episode.

I guess that I am kind of addicted cuz I answered yes to question 1 3 4 5. I have to check facebook thousand times everyday because people may update their page every second. Its becoming a compulsive action of myself to refresh my page like within few seconds. I know there is nothing to do on the Internet but I just don't want to get off line.
