The best advice I was ever given regarding labor pain was that a contraction lasts about a minute- you can make it through a minute of pain and then it's done, you've got time to recover and gear up for the next.
Now- my OB told me that she could give me IV pain meds to "relax" me and help deal with the pain. Well, all that did was knock me out so my memory of labor with DD was one never ending contraction, so I ended up begging for an epidural. Told my OB no IV pain meds this time, I want to try to deal with the pain as much as possible with a clear head.
