Facebook can be very addictive, yes. But it all depends on you doesn't it? It will either run its course and you'll move on, or you'll lose yourself in it. The BEST way to break out is to become an Internet Giver instead of just an Internet User. Put something back on the net, whether it be a website, an article, or just useful posts. Once you get that in your blood, Facebook will shine much less brightly. Keep your real net friends, and forget the rest. Facebook will still go its merry way just fine without you.
