Consistency is key, I've heard time and again and my own experience seems to support (FWIW).

However, perfect consistency is hard to maintain. Even if one avoids the late parties and whatnot, eventually emergencies get in the way or illness comes along and increases the amount of sleep required.

My question is, when consistency must falter, what piece is most important? Going to bed at the same time, getting up at the same time, getting the same amount of sleep, or getting at least some particular amount of sleep? The article here claims it is not the last.
