Did anybody have Stadol during their labor?

I met with my OB today and she encouraged me to think about going sans epidural, based on a variety of stuff. I asked if anything was available to bridge the gap between feeling EVERYTHING and feeling NOTHING (i wish nitrous was offered here!) and she said stadol was great and highly recommended it for this situation.

So, anyone have it? How'd it make you feel? I think i've had one friend who had it and said it was amazing and took the edge off but she could still feel well enough to push effectively
