Yes, I would like to say that the appliance has helped me. I do feel like I have more energy at work. It takes some getting used to. I have turned it up numerous times.
I have had the flu in the last little while and due to coughing did not wear my appliance and I did feel different at work on those days.
Just to mention, my wife says I do not snore when I use the appliance.
