1. You lose sleep over Facebook

"If you're staying up late at night because you're on Facebook, and you're tired the next day, Facebook may be a compulsion for you," Lipari said. "You shouldn't be neglecting yourself because of Facebook."

2. You spend more than an hour a day on Facebook

Pile says it's hard to pinpoint exactly how much is too much time to be spending on social networking.

"I can't imagine that anyone would need more than an hour a day on Facebook, and probably no one needs more than 30 minutes," she said.

3. You become obsessed with old loves

Reconnecting with old friends is one of the great attractions of Facebook, and there's nothing necessarily wrong with "friending" an old boyfriend or girlfriend. But Pile warns that it can get out of hand very quickly.

"One of my clients met up with an old boyfriend on Facebook. They started spending hours and hours into the night talking to each other on Facebook. She made some really inappropriate comments about how unhappy she was in her marriage," Pile said. "Her cousin saw the comments and told her parents, and the parents told the husband, and now they're in the process of getting divorced."

 4. You ignore work in favor of Facebook

"If you're not doing your job in order to sneak time on Facebook, you could have a real problem," Lipari said.

5. The thought of getting off Facebook leaves you in a cold sweat

I thought I was a Facebook addict. I spent so much time on it. I joined Facebook in 2004. After noticing how much time I was spening on it more and more, I decided to give myself a 30-day hiatus, just to make sure I wasn't losing it. My boyfriend would even complain about me being on it consistently. That 30-day hiatus started on Feb 2, 2009 and I have yet to reactivate my account. Although I loved connecting with friends, and displaying my personal and professional accomplishments through the social network, I'm so much more productive without it. It really challenged me to think outside the box. Instead of going home, turning on my comp and spending HOURS playing Scrabble, I would call my grandma or watch a movie. I do eventually plan to join again, but every time I think about how much time I'll spend trying to "catch up" with what I've missed since I've been gone, I decide not to.

I think this is my biggest problem with Facebook. That is a sad story, but I can see how easily it happens.
