I think you should keep an open mind. Don't rule anything out.
TBH you have no idea how you labour will go. You can hope it'll be straightforward but sometimes things do occur to slow things down or cause more pain. Pain relief might be very welcome if this occurs.
I personally am not frightened of the needle or any such thing, but my personal belief is that I would rather try for natural birth over a medically assisted one. Hence me opting for homebirth where things like an epi are not available to me. However if I should have to be taken to hospital for whatever reason I accept I may well be needing more pain relief by that time. I've not ruled it out. My mantra has been 'I'm not ill, I'm pregnant' throughout and I don't wish to have a medically managed delivery unless it really is needed for either myself or baby. I belive that being in an environment I am happy and comfortable in is half the battle mentally. I feel more relaxed about birthing at home and hope this will benefit me.
If you've read one post about an epi experience I'd suggest to do more reading. Everyone has a different experience and I'd not base any decision on one post. I'd do lots more research and discuss with MW and later a consultant about all pain relief options if you wish to try to manage without an epi.
In hospital you can hopefully use a birthing pool which is a great pain reliever and also a good place to actually give birth in, plus gas and air and things like pethedine (needs to be given early in labour however as it crosses the placenta).
You can also practice breathing techniques to help work through contractions rather than tensing and fighting them. Easier said than done I am sure, but its how I hope to be. Also keeping mobile as long as possible in labour is a good thing I am told. Gravity and all that does its bit, plus it means you can get into positions that are comfortable for you. Lying down puts pressure on your lower spine and coccyx and can make baby delivery slower and possible be more painful as you are compressing your spinal area into an awkward shape for baby to move downward.
You will hear all this sort of thing at ante natal classes on birthing and labour so be sure to sign up for them. I think it will help you a lot with possible decisions on how you would like to manage your labour.
Prior to labour you can in the last few weeks do some exercises on a birthing ball to help encourage your baby into a good birthing position etc. Lots of pointers on how to do this and other things can be found on this forum or elsewhere on line.
