With my first, the midwife asked me if I was planning to get an epidural and I answered that I would like to try without. She told me to not say I don't want it because that might mean that I wouldn't be able to get it. Anyway, when I got there, my contractions were very strong after my waters broke and with no time in between (half a minute if I was lucky). Knowing that with a first, labour can take a long time, I asked for it as soon as I got there! Anyway, I was not the usual first timer and I was pushing baby out when the man arrived to give me the epi. It took about 3 hours from when my waters broke till my son was born.
With my second, I found out that I cannot feel contractions (part from the very last ones). I ended up in hospital very early and it was taking long but they didn't ask me to go home because I was in active labour and I livehalf an hour away. They ended up inducing me to speed things up and they asked me if I wanted an epi, which I refused as I could hardly feel the contractions anyway, and I knew when the strong ones arrived that the end was near, and it was, it took less than a half hour.
I just wanted to explain why it is good to have an idea of what you would like but keep an open mind.
I am pretty sure this time that I won't be getting an epi but for my first the only reason I asked for it when getting there was because I "knew" it was going to take hours, and as it happens there are exceptions.
I hope everything will go well for you and that you won't need the epi. It can be done, many have done it and will do it in the future, and hopefully you will be able to go back to all those people who tell you now that you must have an epi and tell them that you went without and that you feel great about it!
