There have been many studies on the benefits of sleep. You must get quality sleep every night Many use conventional medications to sleep as Ambien, Trazadone, Lunesta, and Clonazepam. I usually want people to sleep without the conventional medications as some are addictive and have side effects. I utilize magnesium, theanine, CBD oil and many nervine herbs as Passion flower, Skull cap, California Poppy, Valerian and even Chamomille.
