I had the spinal, and no issues with it. (I did wake up really queasy, but they said that was the morphine, not the anesthetic.) I was basically alert and coherent as soon as I left the recovery room, which was about an hour post-op.
At its worst, the pain was about a 5 - the nurses did keep asking using that scale, too - and that was day 1. After that I'd say it never got past a 3, and when controlled with painkillers it barely registered. (Except for bladder spasms from the catheter, which hit on day 3 and made it all the way to an 8.)
I, at least, had an IV running and they injected the pain meds into that. As far as I know, I got morphine, oxycodone, and Demerol, all of which are available in the US too.

I second the suggestion that being mobile and active really seemed to help speed recovery, and it's certainly Brassard's personal philosophy.
Good luck!!
