I had versed when I had a lower intestine biopsy (to rule out celiac disease). It's actually really cool--one minute I was sitting up in the procedure room as they were prepping me for the biopsy. Then, in what felt like a minute later, I was waking up, back in the recovery room, everythig over.

Although I did wake up very soon after the procedure, I was still woozy, and there's no way I could have driven. My DH drove me home, and I slept on the couch for several hours.

If your PCP is nearby, maybe you could tell them about the appt, and ask if you could hang out a little longer (they tend to push you out as soon as you awaken), and go straight the other appt.
