Three Hours of sleep enough?

So over the past couple days, I've been working this TERRIBLE schedule... and only been sleeping like three hours a night, or so. Today was no different, except I went to bed at 10 pm and layed/lyed (whatever) for a few hours. I know I got at most 3 hours again, and today I'm a little groggy, but not too bad. I'd almost take the bit of groggyness for all the productivity that would add.
