you know that stuff they give you when you go to the dentist and they say "you will be awake and lucid but when this wears off you will remember none of it"? One minute they are giving you the stuff and the next thing you know you are at home watching tv with big cotton pads in your mouth. You've completely lost that period of your life, it's like time travel. I wish there was one that lasted say 50 or 60 years.
