My son uses it during the school week. Without it he would still be awake when I got home from work, I work 3-11 and drive an hour home, on a good night. He was always getting in trouble at school. Never wanted to get up, etc. We give him about 1.5 mg per night of liquid melatonin. He is typically asleep within 15-20 mins, sleeps through the night for the most part, there are times when he hops into bed with me after dh goes to work. He is easier to get up for school, doesnt mope around and try to go back to sleep. It has been a life saver here.
