I did with my medicated hospital birth (4x), but not with either of my unmedicated births.
During my second birth, I felt very hot, and nauseous, and I kept begging DH to turn on the ceiling fan. (He couldn't get it to work.) I think the heat had a lot to do with my nauseous feeling -- I get carsick easily, and one thing that always helps me is lots of cold air.
I was prepared with my third birth. I read that citrus essential oil can help that queasy feeling, so I brought a bottle of tangerine oil with me to sniff in case I needed it. I started feelin nauseated during transition, and the MW waved some tangerine oil under my nose, and the feeling passed within one minute, and didn't return.
I would recommend the citrus oil along with ginger candy and a fan to help cool you if you're really afraid of throwing up. (Also, low blood sugar contributes to that nauseated feeling, so drinking lots of juice/sucking hard candies can help.)
