8.Best: A Low-Sugar Granola Bar
This can be a good stand-in for a cookie, as long as you check the nutrition label. Make sure your bar has some protein and fiber and not too much sugar. Or reach for half a banana and a handful of almonds — both good sources of magnesium, a mineral that can help you wind down. This fruit and nut combo has some tryptophan, too.
