I had GA twice. First time I was 14 and had my tonsils removed. I remember laying in the OR before going under. The Dr. was asking one of the nurses, "Did someone leave this gas machine on?" I was like, WTH kind of place am I in? Then they put the IV in my hand, and I heard him say "Out you go!" I remember waking up in recovery, and as I awakened for a bit I was apparently trying to flail my arms. This must be normal, because they were strapped down. I heard the nurse say "It's ok, you're in the recovery room." Out I went again. I awoke in a hospital room to the sight of my father in a chair at the foot of the bed. Don't really recall feeling like the time was "missing." though.
Second time was having my 3 remaining wisdom teeth removed a few years ago. I barely remember sitting down in the dentist chair. Again, IV stick in the hand, and apparently I woke up and was quite entertaining to everyone, including my father, who had driven me there and back since my wife was at work. I apparently also insisted I wanted pudding to eat, and proceeded to let the pudding fall off of my completely-numbed lips and all over myself. Again, I'm told I was very entertaining that afternoon. But I still don't recall feeling like the time was "missing." Must not have gotten the good stuff everyone else has had...
