"I can relate to the face-in-keyboard symptom -- I was given morphine, once, and I dozed off in mid-conversation."

I can relate to the keyboard, too. Sadly, however, it was not due to morphine or strong prescription drugs. Nope, Nyquil does that to me. My friends won't let me have anything more complicated than a remote for the DVD player when I'm sick enough for Nyquil.
