DEAR DOCTOR K: I have dark circles and bags under my eyes. Does this mean I'm not getting enough sleep?
DEAR READER: Lack of sleep probably has nothing to do with the dark circles and bags under your eyes. In fact, getting too much sleep is more likely than too little to cause this appearance. That's because when you're sitting or standing up, gravity tends to pull excess fluid in your body downward toward and into your belly and legs.
