I got a spinal, and this is purely anecdotal, but I had no problems whatsoever with waking up in the middle (I believe the actual operation time ran under two hours, b/c Brassard usually works in concert with Belanger) or long-term side effects. I was nauseous when I first woke up, but they told me that was more likely the morphine while I was under than the spinal.
And Brassard believes in *feeding* you. 🙂 They offered, no joke, a big steak dinner - real food, too, not hospital food quality - within 3 hours of when I was out of the recovery room. I couldn't eat all that much of it, but I know some of the other women did manage to eat 2-3 hours after getting back to their rooms. I'm afraid I didn't feel up to inquiring about the logic behind it, unfortunately, but I do know that at least nobody got sick from trying to eat too soon.
