I kept an open mind about pain relief during labour and I am so glad I did (though I wasnt keen on the idea of any pain relief) I ended up having a meptid and a epidural (and some gas and air but only after arguing with the midwife that I didnt want any at all)
if I am honest, labour for me was awful (I had my baby two weeks ago) I was in labour for 15 hours (when my waters broke my contractions straight away were two and a half to three minutes apart and lasting for nearly a minute) and pushing for two and a half hours and ended up having a ventouse and sadly it has put me off having anymore children

I was in loads of pain and nearly ripped the OHs top (though I didnt swear or shout at him!) and was nearly crying with the pain and nagging him to get them to give me pain relief as I couldnt take anymore!
You get through it and as everyone says everyone is different, you might not find it that bad!
