Sleep disorders are no laughing matter. But they are usually treatable. That's the topic of Saturday's Deseret Morning News/Intermountain Health Care Hotline. From 10 a.m. to noon, Dr. Robert Farney, medical director of the LDS Hospital Sleep Disorders Clinic, and Dr. Tom Cloward, a sleep specialist there, will take phoned-in questions. The toll-free number is 1-800-925-8177.
