I had an epidural with my first, and nothing but the gas with my second.
It was hard, but as soon as the baby is out, it ends so siddenly that it's hard to believe it was happening.
I didn't tear either time, and to be honest, I never bothered with all the excersizes massage etc that they recommend.
It's true you cant feel to push with the epidural, I couldn't feel a damn thing- I just thought about pushing real hard, and hoped something was happening - the baby came out, so I guess I managed a few pushes !!!!
It was funny, they were saying wait till you feel another contraction, and then push- I couldn't feel a damn thing, so I just pushed- or thought "push" at random.
Good luck either way.
