Hon, no-one here would object at all - as long as you're going to stay on here and entertain us of course. You have to do what's right for you but, as Catz says, just beware that you don't end up dabbling between plans and making no progress.
If you were going to do something like Lipo or CD but only short-term, I'd suggest doing it for a month rather that two weeks and then coming back to WW.
