For me, the experience has been a lifesaver. Going into this I was not sleeping much at all. Now I sleep through the night at least 4 of 7 nights. Dr. Stern very understanding about my situation and was patient about adjusting the appliance to work for me. My situation was especially stressful because I have a compromised airway. Dr. Stern's staff is very helpful; they all worked with me to improve my personal situation. This treatment worked!! Thanks!
