anesthesia
"I went in for a colonoscopy today and was put under with propofol. It took affect right away ...after maybe four deep breaths. I was groggy for Maybe 15 minutes after waking up in recovery. However, I have been suffering from major allergy like symptoms all afternoon and evening...sneezing, watery eyes, congestion, then nose running. Feel fairly miserable...not from procedure but from sneezing."
