Someone with insomnia will often take 30 minutes or more to fall asleep and may get only six or fewer hours of sleep for three or more nights a week over a month or more.
If insomnia makes it hard for you to function during the day, see your doctor to determine what might be the cause of your sleep problem and how it can be treated. If your doctor thinks you could have a sleep disorder, you might be referred to a sleep center for special testing.
