If you answered yes to this question, you are not alone. Insominia – difficulty falling asleep or staying asleep, or not feeling refreshed when you awake in the morning – is estimated to affect more than 73 million Americans. And research has shown that one in every six adults consider sleep to be a serious issue in their lives. Most people affected by insomnia have never brought the problem to their health-care professional1s attention, possibly because they don't think of it as a medical disorder. Yet trouble sleeping, like trouble eating, breathing, or walking, can have a major effect on your health and well-being. Your health-care professional can help.
