Same here. I used FB before news feed, when it was still restricted to colleges.

I was afraid to quit, because was worried of losing some information, and contact with friends.

The crazy things is that once the account was gone I realized that it was addiction. I don't feel like I lost anything. Also the friends that I cared about an able to communicate with them using alternatives, and the others I never really talked to, so that also was a false fear.
