If you're having trouble sleeping try GABA 2 hours before bed and L-Tryptophan 1 hour before. No phone or computer screen from the time you take the GABA til morning. Have a totally dark room and make sure it's cold. Taking a hot shower makes your body temperature dip which is what will knock you out real good as well.
Don't take NyQuil for sleep unless you're sick.
