Missed Sleep

The average human can function for a 16-hour “day.” He must then rest for an eight-hour “sleep period.”
If you’ve been awake for more than your normal day (typically 16 hours), you start to get tired.
You lose 1 FP if you fail to go to sleep, and 1 FP per quarter-day (usually four hours) you stay awake after that.
If you’ve lost half or more of your FP to lack of sleep, you must make a Will roll every two hours you spend inactive (e.g., standing watch).
On a failure, you fall asleep, sleeping until you are awakened or get a full night’s sleep.
On a success, you have -2 to DX, IQ, and self-control rolls.
If you’re down to less than 1/3 your FP due to lack of sleep, roll as above once per 30 minutes of inaction or two hours of action. This can be very dangerous!
