C.,
I had one each, and I can't say that I prefer either one. However, with my first son, (epidural)they "knocked me out" while they stitched me up, and I slept for hours. It was a long labor and emergency C-section, so I am not sure if that had anything to do with it or not. I didn't like that part because I had to wait sooooo long to see my baby.
With my second son, the C-section was planned...no labor, no big ordeal, just go in, lean over, get the spinal and five minutes later they were pulling the baby out.
I can say that I didn't like how "numb" the spinal made me feel. I am short, and they must have given me a lot of the medicine because it numbed me way up into my chest and I felt like I couldn't breath, so I started to panic a bit. However, on the flip side, I felt more "discomfort" through the labor process and C-section with the epidural.
I wouldn't choose either one, If I had to do it again, I guess I would go with whatever the doctor normally uses.
