I'd second the above with regard keeping as active as possible, it definately helps though it can be hard if you are in alot of pain. I found my birthing ball fantastic.
My main one would be to keep focussed, things started to slow down for me when I started to lose it. Keep your mind focussed on the prize of your baby at the end of it, and count each contraction as one step closer to it. The moment I stopped thinking that way the whole process slowed down.
Epidurals also can give you a slower recovery, my friends who had them had to stay in hospital a couple of days after birth wheras I left less than 12 hours later.
Good luck xxx
