I removed all of the applications and games fro my FaceBook account because I was addicted to it. Still addicted to FaceBook, but I think that's because my girlfriend and I are long distance and she sends me messages trough there through out the day.

Still, removing those Farmville and other games was was one of the best things I've ever done.

Good luck with limiting your FB time. I think it's a cool site, but it's good not to be on it all the time. I'm trying too.
