I had bad luck with a failed epidural with my first son and I had my second with no painkillers. The second birth was infinitely more bearable. I had a couple of sessions (private) with a hypnobirthing coach and the whole experience felt very under control.
You might be surprised, especially with a second birth - and it sounds like your labors are fast. Either way, good luck! There's no shame in getting an epidural either. Have you discussed the earlier experience with your doctor? I know there are narcotic painkillers they can give, too.
