Narcolepsy
From NsdWiki
Expoint Bonus: 6
A person with Narcolepsy is likely to become drowsy or to fall asleep, often at inappropriate times and places. Due to a slight malfunction in the brain and the pattern of sleep during the night, a character will suffer intermittent bouts of slumber throughout the day, and waking during the night. Whenever the character rolls a Critical Failure, he or she immediately falls asleep until their next turn.
This fault is especially dangerous when mixed with either Clumsy or Magic Dunce.
