Someone who uses a few days a week (not necessarily daily) as opposed to, say, occasional all-nighters before an exam. For example, mrleinad's comment:

It even helps with going to sleep earlier, because I feel depleted by 10 PM, so there's less incentive for me to stay up and waste time that I could use resting for the next day.
