Afraid so , very many do of course, if they take a break they still yurn for the excitement although I suspect the alcohol together with the comradery of pals in a similar predicament plays a big part, and many do return.
Of course many don't, either leaving that episode of their lives behind simply accepting that is something they needed to do at the time, generally for family support reasons. Of course they still miss the buzz, but can come to terms with a more normal lifestyle, that's not to say that when an opportunity presents itself for an occassional visit with BF/husband later that they have forgotten how to let their hair down.
The sad ones of course are those that can never leave, possibly in with a bad group and/or boyfriend, introduced to drugs etc. I wonder where those poor girls finally end up once the drugs and drink have taken the toll on their looks ?
