Well, I am a doula so I didn't vote
I can say that I have never had a client with an epidural but I have had a couple opt for stadol which I encouraged them to do based on our pre-birth discussions.
I think more women than we realize are unsatisfied with their epidurals. They complain of itching, breakthrough pain, nausea, not liking the sensation of not being able to move their legs. But then like everyone does- after the baby is born they focus on the baby and forget those negatives. They are unaware that laboring med free is a fairly achievable goal because of the horror stories they hear.
With both of my births I opted to have spinals. I went in each time hoping to go natural and gave in to wanting pain meds. I really regret it becuase it made me nauseated, loopy enough that I can't remember much, sleepy, itchy, etc. I would have been much happier without the meds even though no one pressured me to get them. I take that with me to births and try to be true to the woman's desires within the situation.
By the way, DONA's motto is "a doula for every women who wants one." A DONA doula is supposed to support a woman's desires whether it is an epidural at 30 weeks or to give birth hanging from a tree in the rain forest.
