I just to want to throw in that as far as addiction goes, you have to know yourself in order to know whether that is a concern. I've been on hydros before (not during pregnancy) for about 2 weeks following a car accident, and never had a problem stopping them. If you have an addictive personality regarding anything Alcohol/ Cigs/ Pills, of course it would be best to stay away. However, if you typically are someone who follows the package directions to a T, I wouldn't really worry about forming a dependency on it. Of course as with the nature of the pills, if you take it daily for a longer stretch of time, you'll feel off when you stop taking them. But if you're pain is bad enough that the doctor felt the need to prescribe them, taking them for a night or two to get a bit of sleep isn't going to form a habit. Not to push pills on you, but it does sound like you're experiencing quite a lot of pain. They can even be split in half if you wanted to ease into it.
