anesthesia
"I had a colonoscopy today and was given Propofol. As soon as the Anesthetist administered it, I started to taste it, then felt numbness in my chest, closed my eyes and within seconds was asleep.  I woke up when the procedure was done and the Anesthetist asked me who Valerie was...apparently I was speaking about my daughter while asleep. Didn't wake up groggy or anything. Just hoping I didn't embarrass myself sleep talking!  "
