Update, he's gone to the doctor and did a sleep study. Has sleep apnoea, now onto the next step. It was very kind of him to do all of this.
Hurrah! Not only is this going to make a difference in his snoring - but he is going to
feel so much better. People with sleep apnea do not realize how much oxygen is being deprived from their bodies. He will have a ton more energy, and better sleep, too (not to mention yours.)
My Dad suffers from sleep apnea - his had gotten so bad that he was falling asleep in the car A LOT! He even had a wreck from dozing off at the wheel. He's had his machine for several years now, and it has made a huge difference. It even made a change in his blood pressure! His apnea is from being overweight, though. He's going to have the gastric bypass done like I had.
