Don't know if this is typical for all procedures now, but all I remember was about 30 secs in the procedure room counting down(done at the doctors own facility, not the hospital)--I don't think I reached 97 from 100--don't remember a thing. My wife said it was like trying to wake the dead when I was in the recovery room/cubicle. Just remember, when you take the flushing liquid, don't stray far from a restroom for a while. I made myself a big batch of sugar free(I'm diabetic) Jello and could eat that to my heart's content the day before. I did ride the day before as I was permitted some yogart. And yes, lunch was just wonderful after not eating for more than a day.
