Switching to natural birth!

I am currently 23 weeks and all along had thought I would walk into l&d asking for my epidural ASAP haha. Recently I've decided that I want to ahead and try to deliver naturally. My hospital offers the option of laboring in a jacuzzi tub which helps tremendously through the whole process. I also like the idea of being able to move around during labor. Anyone give me some positive pointers on how to achieve a successful natural birth? I am still open to the idea of asking for an epidural, I just would prefer to not be offered one.
