Then my doctor suggested a sleep study (my dentist had already recommended one due to my teeth grinding). I did it. Ended up getting a CPAP - and that's been a life-changer! I instantly felt at least 10-15 years younger, was able to think more clearly, my wife has been able to get good sleep. In fact, I went from being able to wake up everyone in the house with my loud snoring to my wife checking on me through the night to make sure I'm still alive because I'm now so quiet!
I absolutely love it! The machine itself is whisper quiet. I use nasal pillows instead of the face mask and it's very comfortable. Takes a couple of days to get used to, may have to adjust the settings on your unit to make it work for you, but boy is it worth it!
