5 Send stress packing with the lull-yourself-to-sleep supplement!

Worries or other stressful thoughts keeping you awake? Take at least 400 mg. of the amino acid L-ornithine (such as Vitacost L-ornithine, $8.59 per 100 500-mg. capsules, Vitacost.com) an hour before bed! ✤ It works! Research in the Nutrition Journal shows that this amino acid nixes anxious nighttime thoughts by curbing stress hormones and triggering relaxation—without causing next-day grogginess the way sleeping pills can!

And follow the one-hour rule!

One hour before bedtime, stop texting, playing video games or watching action-packed TV shows or movies. Too much mentally stimulating activity right before bed is a common reason women find it difficult to fall asleep, reveals a recent study in the journal Brain Sciences.
