 You just can't take a supplement and think everything's going to go away. Sleep hygiene is really an important factor in anyone's sleep-wake cycle. So making sure your room is at a good temperature, it's nice and cool. It has to be dark. You can't have any blue light around, so you've got to get your cell phone away from you. You've got to put your iPad away. You've got to shut the TV off, read a book, listen to some calm music.
