insomnia
"My son is 5 years old, he is autistic his doctor said to try melatonin. I give him 3mg at night 30 minutes later he is sound asleep. It has been great. No more fighting him to lay down. I was scared to use it, but now i know it works. He hasn't slept good since he was born. Before melatonin I felt like I still had a newborn, waking up and not sleeping. I highly recommend this for autistic children, of course check with their doctor first.  "
