Of course it is doable!! But that doesn't mean that if you do choose to have an epidural when the time comes then you have somehow failed yourself OK.

The small country town hospital where I gave birth do not do epidurals anyway so all birthing mothers who go there do not have any choice about the matter, but if circumstances change and you need a c/s then you have to go under a general anaesthetic. Although I do know of women who have decided to go on to the next big town with a base hospital just so they can have an epidural.

If you know what you want then go for it.
