Dear Dr. John Herald,
I want to thank you for your effort and time in providing a solution to my chronic health problems associated with snoring and sleep apnea. My wife thanks you as well. My snoring not only had a negative effect on my nights sleep but also prevented my wife from getting a needed good nights rest. My snoring made us both irritable in the morning. I would wake up feeling more tired, even exhausted than when I went to sleep, the lack of oxygen was affecting every aspect of my health including decreased sex drive and increased weight gain. My memory was noticeably decreased and ability to focus on a task reduced. My wife and I now wake up refreshed, energized, focused and ready to start the day on a run. I have tried four other Dental Appliances all of which were inferior to the Pro Plus Dental Appliance. The Pro Plus Dental Appliance is far superior in form, fit and function. I can even drink and talk with the appliance in my mouth. It is easier to put into my mouth and I wake up without the jaw pain from muscle strain and poor fit that I experienced with the other appliances.
