Your eyelids weigh ten pounds. The buzzy feeling travels from head to toe. It's time to find a comfy spot, lay your mind to rest, and slumber for a few. You think, "I'll take a quick, 20-minute nap." You don't think, "It's now 3:35. If I want to wake up in 20-minutes, I should set my alarm for 3:55. And that's 3:55PM, not AM." Who wants to fumble with the hour, minute, AM/PM dials when going down for a simple nap? Quickly set your Napt duration then Godspeed on your way to restful slumber.
