I would try my absolute hardest to go unmedicated, only because for me, the effects of the epidural were so negative! Every woman is different, and I have friends who do fine with the epidural, but I'm a lightweight and it really gives me a "drugged up" feeling that makes it incredibly difficult for me to concentrate during labor, which I find more comforting than pain relief.
I will be honest, during transition, I deeply regretted not getting the epidural. That lasted just under two hours of the total experience. My recovery was much quicker when I went epi-free.
