Quoting 2 Baby Girls:" Horrible until I got an epidural. Then it was a cake walk. I dilated from like a 5 to 10 in 40 minutes. ... [snip!] ... to 10 in 40 minutes. I'd been in labor all day and only dilated 1 cm. My body just wouldn't relax. The epidural did it for me."
Basically this. Went from a 4 to a 10 in a little under half an hour after getting the epidural, started pushing half an hour after being checked. [They let me rest for awhile before pushing.]
I loved the epidural, it made me feel really cold though, I was under like 5 heated blankets and I was still shivering and felt freezing. SO said I felt really hot though lol.
