Insomnia is a common sleep disorder characterized by an inability to fall or stay asleep or both.  As a result, you may get too little sleep or have poor-quality sleep and wake feeling tired or lethargic. Symptoms of insomnia include:

  • lying awake for a long time before you fall asleep
  • sleeping for only short periods
  • being awake for much of the night
  • feeling as if you haven’t slept at all
  • waking up too early


Your doctor will diagnose insomnia based on your medical and sleep histories and a physical exam. He or she also may recommend a sleep study to measure how well you sleep and how your body responds to sleep problems. Treatments include lifestyle changes, counseling and medication.
