@ElizaBennett - I agree with you that pitocin contractions can be on the intense side! I tried having it during my interminal labor, ending in a C-section, with my first childbirth. It hurt like crazy, so I did wind up getting an epidural. I'm sure it works for some people to speed things up, but for me it did nothing at all - my baby was *stuck.* I also remember them giving me more pitocin in the OR because my uterus was not as firm as they wanted and I guess they were worried about bleeding.
I was able to deliver vaginally without medication the second time, and it was a much better experience. Both times, I really noticed the release of oxytocin from breastfeeding! It's how I knew baby was really latched on right, that powerful spasm I felt. Almost painful.
