anesthesia
"Had a preventative ( first one cause over 50) colonoscopy yesterday. It took a little longer than usual as they removed some polyps so they gave me a very large amount. I woke up during the last 5 or 10 minutes of the procedure. The day after (today) I had to leave work because I could still not focus or concentrate and I feel weak.  Hope it goes away soon!!!  I have to think at my job as a machinist and could not comprehend the match I have to do today."
