anesthesia
"I had propofol for cataract surgery combined with another drug.  I was very dizzy and slept most of the day after the procedure.  I am now four days out and still feel very fatigued - napping - which is unusual for me.  I woke up during the procedure (which is expected) and the room was spinning.  Are these things normal?  I had the propofol for colonoscopy and did not experience any of these things."
