Well, I'm glad we sorted that out, cause Merc's post confused the heck out of me too.

I will adopt (I think it was Monster's) reading of Your Mean Tome. It works for me.

I had a student who missed tutes due to a form of narcolepsy, she didn't drop off suddenly, but could simply fail to wake up, sometimes for days. She would eventually wake, starving hungry, dehydrated, generally feeling shit.
Still, narcolepsy + guard duty = problem.
