anesthesia
"I had a colonoscopy and the anesthesiologist used Propofol. When I woke up I wasn't groggy and my mind wasn't fogged. In less than an hour after the procedure, I was able to use the restroom, get dressed, and walk out of the hospital without assistance. We went to a restaurant, went to the mall to shop, and I was so clear I couldn't believe it. This would be my anesthetic of choice."
