Shell-Although I havent given birth to twins, I have had an epidural. I was one of the people who was completely adamant that I would not have one, but am glad I did. They gave it too me in amongst my strong contractions, so I didnt feel a thing.
Have you thought about asking them to see how the labour is progressing before they put one in and if they do, can you request no drugs be put through until absolutely necessary.

2nd needle was fine, no where near as bad. My hips and pelvis though are loosey goosey and causing havoc.

Take care ladies.
