**Facebook addiction**

Since I have been on Facebook my grades/success on work have deteriorated/my performance at work is worse.

It happens to me that I sleep much less than usually because I stay longer with Facebook.

Sometimes I have an impression that I live two lives: one private and another virtual.

I would rather spend an afternoon and/or evening on Facebook than devote that time to any other activities.

I have better time with people that I have met over Facebook than with those that I know in person. I fear that I might meet some of my virtual Facebook friends in real life.
