I read that the other way from the parent - in that you should keep drinking until your pee is clear. Then you're back to "normal" after a dehydrating event (the workout), so you can continue maintaining that level as normal. And I agree that "constantly carrying the bottle" has become as much about the fashion as anything - there's a guy at work who always has a metal bottle on him, taking it everywhere. But they rarely use it - they've never refilled it at work, and less than 1l (I've never seen it less than half full, but assuming it is used over the day) over 1/3 of the day doesn't feel like theyre over hydrating.
