Unfortunately, I have no advice. What I DO have is sympathy. I am going through the EXACT same thing with my 13 year old (who happens to be named Lauren as well).
What gets me is there is NOTHING that seems to work. Once I threatened to not let her attend a school dance and that seemed to do the trick, but there aren't always school dances to threaten with, you know?
