What Is Insomnia?
Do you have trouble falling asleep? Do you wake up often during the night? Or, maybe you wake up too early in the morning. You may be suffering from insomnia. Talk to your health care provider if it lasts longer than a few weeks and you feel tired most of the time.

Medical problems such as pain, depression, medication side effects, or trouble breathing
Circadian rhythm disorder, a shift in the body's normal 24-hour activity cycle
