Sleep study?: Have you undergone a sleep study (polysomnogram)? Sleep disturbances may be representative of a neurological condition. Discuss with your primary care physician, and if your symptoms warrant, he/she will refer you to a neurology or pulmonary sleep specialist. http://www.nlm.nih.gov/medlineplus/sleepdisorders.html , http://www.nlm.nih.gov/medlineplus/ency/article/003932.htm
