Catching the Zs, penelties for no sleep? Options

[Karaden]

I was just reading through the book a bit, and noticed that there are several mentions of taking penelties of some kind, but these penelties are never actually mentioned directly.

Is it that each day that a character goes without sleep he takes 1 point of stun damage as per the fatigue rules, thus allowing the average person to go 7 days without sleep if forced to (Which is actually fairly accurate as to the max a person can go without sleep, though they'll be halusinating and such)

And since sleep regulator says "...and stay awake for 48 hours before modifiers start to take effect." does that mean someone with a sleep regulator could stay awake 14 days before dropping?

I know this doesn't usually come up, it is assumed characters sleep at some point and everyone is happy, but I'm sure there are times when you really can't sleep. Maybe you have a timed cortex bomb and you need to do stuff before it goes off, or maybe your on your own and can't risk getting caught in your sleep, or any other number of possible reasons.

So, in these cercumstances what sort of 'modifiers' should be applied? 1s damage every day just seems like far too little, I'd rarely have my sleep regulated character sleep more often then once every 6 or so days just because of how efficent it would make him at extended tasks like programing.

Personally I think a -1 or -2 dice pool modifier should be applied to all skills for each day that you go without sleep. What does everyone else think about this?
