anesthesia
"Went for colonoscopy after 12 year delay. Newer anesthesia than the earlier one. Propofol. Just great. Out in a few seconds as I was saying I could feel it taking effect. Next I was being awakened in recovery. Groggy for maybe 10 minutes. Thank full it was over. Sorry for those who had bad reactions because for most of us it is the perfect twilight procedure drug."
