Having long term sleep issues my medical doctor suggested I see Dr Muir. I was tested for sleep apnea with a device strapped to my chest while I slept at home for one night. I had Moderate Sleep Apnea and never knew it until then. Dr Muir fitted me for a mouth appliance and then retested me and my sleep apnea scores were much better. More importantly I felt good when I awoke in the morning, morning headaches were non-existent and I stopped taking a sleeping pill at night. I now sleep 7 hours nightly, rarely waking up and have so much more energy.
