Any advice for a natral child birth?

I am 26 weeks pregnat with my forth child. This will be my first attempt at an unmedicated childbirth. I had epidurals with my other three, one of which didnt begain to work until after the baby was born. Being as I am a bit older and wiser now I decided that having a large needle stuck in my spine follwed by a plastic tube and a steady flow of narcotic wasnt a good idea. I've read up on Hypno-birthing, Lamaze and all kinds of other techniques to help with a natral birth... So what worked for you? Any advice would be so very appreciated! Thanks in advance!
