What to Do

If you suffer from Insomnia, see your physician or one of our board certified sleep specialists who can help identify the type of insomnia you have and the cause. Usually Insomnia will be diagnosed based on your medical history, your sleep habits and a physical exam. A polysomnogram (PSG), which is an overnight sleep study, may be recommended. Lifestyle changes can often help relieve short-term Insomnia by making it easier to fall and to remain asleep. A type of counseling called cognitive-behavioral therapy (CBT) can help relieve the anxiety linked to chronic Insomnia. Your doctor may also prescribe one of several medicines that can also help to relieve Insomnia and re-establish a regular sleep schedule.
