So it was quite a relief for me to read that this 8 glasses a day thing has been debunked.
The New York Times:
"Contrary to many stories you may hear, there’s no real scientific proof that, for otherwise healthy people, drinking extra water has any health benefits. For instance, reviews have failed to find that there’s any evidence that drinking more water keeps skin hydrated and makes it look healthier or wrinkle free. It is true that some retrospective cohort studies have found increased water to be associated with better outcomes, but these are subject to the usual epidemiologic problems, such as an inability to prove causation. Moreover, they defined 'high' water consumption at far fewer than eight glasses."Finally! One less thing to feel guilty about not doing right. What the author, Aaron E. Carroll, a professor of pediatrics at Indiana University School of Medicine, points out, is that most of us get plenty of hydration from the food we eat as well as from what we drink. Fruits and vegetables contain water, for instance. As does any beverage you can think of.

It's not just the calories, either. It's the caffeine, and the chemicals, and the alcohol, that we're better off without.
Personally, I think staying on top of one's water consumption is important. It's too easy to go an entire day and at the end of it, realize, "Hey, I'm really thirsty--and I've BEEN really thirsty for A WHILE now."
So, how DO we keep ourselves properly hydrated throughout the day? I can't vouch for the accuracy of the healthful effects stated here (they do seem a little sketchy), but I think this infographic (below) is a pretty good schedule for keeping on track, nonetheless.
