My husband has been exhibiting Rem sleep disorder for about 5 years. Recently, after slugging me in the middle of the night, he agreed to have a sleep study. He first was seen by Dr. Robert Hooper at Mayo Clinic. Dr. Hooper published a book that we are currently reading called Sleep and It's Disorders What you should know. It goes into these violent outbursts with some people and how to treat it. He will go over his results at Mayo in 2 weeks with a sleep specialists and a respiratory therapist. I was just diagnosed with Central and Obstructive Apnea. He has seen the improvement in my sleep and I do believe that this motivated him to finally get help. For the past 2 days, he has been putting tape on his mouth when he goes to sleep. For the first time in several years, he was not snoring throughout the night and had less movements. Dr. Hooper did mention that he might benefit from using Melatonin. Will follow up with everyone when they go over his results.
