Ok, well, let me say - you asked for it!
Kid no. 1 - Had pain meds. This is the one where I had myself convinced the pain was mostly in my head. And it didn't feel "painful" to me in the conventional sense, just intense. I did eventually get a shot of medication (although it's been so long now I don't remember what it was). It did help me relax a bit between contractions but that was it. Did absolutely nothing else. I had a local anesthetic administered before she came out. This was because they were trying to prepare me for an episiotomy but I was too fast and pushed her out before that happened. I felt tired afterwards but it wasn't because of the meds, it was because I had been UP for well over 24 hours. Or maybe it was the meds, don't know.
Kid no. 2 - I had a couple shots of something (again don't remember what it was). It did absolutely nothing for me. What happened is that my daughter came out and she was lethargic and not crying and when I tried to breastfeed her after she couldn't seem to suck very well and I could not get my eyes to focus. I believe all of this was a consequence of the drugs.
Kid no. 3 - I decided screw it...meds never helped, I was not going to have an epidural and so I was going "au natural". It was my best birth because rather than try to "fight" contractions, I just went with them and flowed with them. I had no meds, no nothing. She came out, she cried, she nursed like a champ and I was up and out of recovery in 20-30 minutes, which I was told was a hospital record. I got a rush of endorphins that just left me feeling GREAT and I recovered so much more quickly than I did with my first two.
I did have an epidural when I had a D&C for my first miscarriage. I didn't like not being able to feel my legs.
I would never tell anyone to not get an epidural, but do encourage ladies considering it to really research it and think about it mostly for the reasons that Melissa gave. It is not uncommon that women who have epidurals find their labour slows down. Then the doctor will want to give the woman pitocin to speed the labour back up. So now there's 2 meds running through your body. Some women (not all) will find it makes their ability to push a bit sluggish and like Melissa, it takes them longer to push the baby out which may lead a doctor to want to use forceps or vacuum extraction to assist things along.
Of course, though, the other side of it is that many many women have had epidurals, loved them and would not ever give birth without one. It's a matter of what you prefer.
There's a lot of books out there that details different methods to cope with pain in labour. A search on Amazon will lead you to them. As I said before, now is a really good time to formulate a birth plan and think about what you would like and not like and make sure your care provider knows and understands them. Best of luck girlie!
