Honestly, it's REALLY not that bad.
And this is coming from a woman who was in labor for 33 hours, and had been flat on my back for 10 days prior to going in to labor, save for sitting up to eat and going to the bathroom.
I chose to go pain killer free for several reasons (although I did get one mg of Stadol at hour 31 which lasted 20 minutes and got me through transition and then just stopped working...
1) I didn't want my 30 week preemie to come out drugged and at any more of a risk than she already was
2) I wanted to experience everything my body was capable of
3) I'll do it again with this baby, because I felt like a complete and total rock star after delivering DD, and I was able to get out of bed and walk to the bathroom by myself immediately post partum
Honestly, it was mostly selfish reasons. The anesthesiologist told me he didn't think I could do it drug free, because it's "hard to deliver a baby", and I basically wanted to tell him to bite me, so I made sure not to ask for an epidural. And I was terrified of the spinal headache, blocks, and ending up numb from the waist UP like a woman I know.
Alright, I'm rambling. Sorry!
