> Before it's grown to your whole arm, you've vanished
I wonder about this bit though - I wasn't sure if I really had gone out that quickly, or if I talked for more time but just don't remember it.
After my operation I apparently woke in the recovery room and said some things (I heard the nurses talking about it afterwards) - but I have no recollection of it at all.
Also, you're spot on about the passage of time - when I finally woke and was actually lucid (well, fairly!), it really felt like no time had passed.
