I did with my medicated and non-medicated birth. I puked just a small amount with the unmedicated, a couple small heaves ....with my medicated birth it was a couple of big heaves......
Just "yes" and "no".
The worst part for me would be anticipating it. I know I sound nuts to lots of people, but vomitting is one of my top 3 scariest, awful feelings. So many people (DH included) remind me of how much better you feel afterwards, but I just CANNOT get myself to think of anything other than "please God, I don't want to puke!" And I can't imagine adding that into labor!!:
