one thing i know from not using pain medication during my birth with my son is that just when you think the pain is getting bad, your body comes through for you and raises the pain tolerance that you can handle. there is no reason (other than the extra money for the hospitol and person administering the epi) that you should have to have one, you should be ok. there ARE other options!! immediatly ask your doctor what ALL of the options are for pain medication. around transition (you do know the process of birth and the stages right?) transition is the "worst" period during a birth. the contractions really intensify and come almost right on top of each other. i asked for some sort of relaxer. it made me feel half asleep between contractions, and by the time i was pushing it wore off. it was great, even when they only gave me half doses the whole time i needed it.
ask your doctor all of the other pain options. epidurals werent even offered in my clinic. so i know there are a bunch of others.
www.askdrsears.com might have some information for you - im sure that one of dr william sears books (the birth book) has a list of medication that can be used to ease pain during labor
if you need some support, just want to talk, or if you really want some more information please do not hesitate to send me a message. ____@____.com is my email address, i would be happy to help you any way that i can. you CAN do it without any drugs, especially considering the reaction you had the first time. there is no reason to risk it again. :)
also, its probably not too late to hire a doula who will be of GREAT help during your labor. sure, they might be costly, but if you really think you need the support, give it a try. i dont know how to get ahold of one, but if you go to www.llli.org and search for a local or nearby la leche league group they might surly know of a doula or someone who would be willing to help you out. :)
