You know those nights when you're trying to fight the rumbling in your tummy right before bedtime? I've been known to stay up late for a deadline and wander my way into the kitchen in search of a quick and healthy snack. When it comes to nighttime snacks, it's best to reach for something on the small side that also has staying power. The right nighttime snack (and possibly even a nightcap!) can significantly impact how you sleep and consequently how you feel the next morning.
