labor pain
"I am literally on this medication right now. I got a dose through my IV and yes at first it was intense and made me very loopy and hot. But now I am just must more relaxed. This is my fourth baby. I'm not quite full term so they used this to see if I could relax enough for contractions to stop. They haven't and I can still feel them but it's much more bearable now. I didn't have this with any of my other deliveries just the epi. 
Everyone reacts differently to different medicine and doses, so I don't think that basing what is right for you off of other people's experiences is a good idea."
