I am writing this because there is no one more skeptical than me, but I knew I was having trouble sleeping and I did not want a bulky CPAP machine. So I took the test and got fitted for the device. Then I went home and gave it a shot. I WISH I HAD DONE THIS YEARS AGO! It only took a few days to get used to the device in my mouth and I noticed immediate results. I was sleeping through the night and waking up more rested and able to get up and going faster. I’ve also had improvement in my back pain due to the fact I’m sleeping deeper and not tossing and turning. I also have more energy late in the day whereas before I’d be yawning by 2pm and not knowing why I was so tired. As I said, I wish I knew this device was available years ago. It’s been life changing to say the least. My girlfriend also loves the fact that I don’t hardly snore anymore. Big thumbs up for her as well. I am so glad Dr. Drake and his team took the time to go over and explain everything to me and made this possible. You have nothing to lose and yet so much to gain by getting one these sleep devices.
