Is there a reason why I pee more when I stay up all night working?

Do you drink more caffeinenated beverages (which are diuretics...)?

More or more often? Maybe the total volume is the same?

Umm ... I think it's because you are awake and conscious of the sensation of having to go, or am I not understanding your question?

second on the caffeinenated beverages- you can hear about their 2:1 effect on urine production in the boingboing.net video stream about the stolen laptop.

I tend to get very hot when I have to work an all nighter, whatever the temperature is. I can't say I've noticed any difference in urination though.

Stress can make you want to urinate. Staying up all night causes stress. (IANAD)

caffeine or adderall, maybe?

When you sleep, some of the water in your urine leaches back into your bloodstream. (I seem to recall this function is actually activated by a sleep hormone.) This is how you make it through the night without peeing, and why your urine is often darker in the morning.

Caffeine is a diruetic, so if you're drinking any of that, then what others have said.

When you are awake or asleep your bladder fills with pee. When you're awake, you go to the bathroom and pee but when you're asleep your body makes a hormone called vasopressin. Vasopressin (or vaso as it is sometimes called) concentrates the urine. As I understand it, when you drink alchohol the the creation of vasopressin is inhibited. So when you're drinking you're 1) filling your body with liquid that you'll eventually need to pee out, and 2) you're keeping your body from making vasopressin so you'll have to pee that beer our sooner. Think "popping the seal."

Additionally, Vasopressin is a "smart drug" used to get a clear head and learn new things (as opposed to memorizing things you already kind of know...)

While you might want to consider the source (the study was funded by the National Coffee Association) new research shows that caffeine is not a diuretic.

Yeah, vasopressin was what I was thinking about.
