I don't want to sound like a broken record, but to re-enforce the consensus in this post and I hope this helps (as it did for me) is that what pushed me into getting an evaluation and a sleep study done was my daughter. I recently became a dad for the first time and a few things dawned on me and one being of me hoping to be alive and in the best of health when my daughter grows up. I'm not as young as I would like to be, but I also know I'm at the half way point through life. As for my sleep apnea, I knew about it for a very long time but didn't bother with it (initial fears, embarrassment, inconvenience, etc.). The more I became aware of what sleep apnea is and the potential consequences to my health and factor in me being in my daughter's future, I took a leap of faith with the intent of doing something about my health and well-being (not to mention keeping my wife happy from my snoring). Long story short:
1. I am overweight.
2. Doc did not find any indication of diabetes (even though it runs in my family).
3. I have large tonsils, large tongue and a crooked septum. Issues that contribute to snoring, including my overweight factor. I can get surgery done to "fix" these physical problems.
4. I had high blood pressure (160/110).
5. The sleep study I went through diagnosed me with severe sleep apnea. Meaning, I stopped breathing about 200 times during that study. Not good.
6. I always felt tired. Getting the day started with like pulling teeth. I didn't get warmed up until late in the morning and then started feeling sleepy/tired by around 5 p.m. Could not focus a whole lot at work (which caused self inflicted stress).
After prescribing and getting fitted into my beloved cpap...
1. No more snoring, according to my wife.
2. Feel rested. I actually remember dreaming every night now...I can't remember when was the last time I dreamt so much...probably when I was a teenager. More focus at work (my peers and boss are very pleased). I get up in the morning with no issues - change a diaper, brush my teeth, eat breakfast with energy to start the day. I get home from work and have the energy to walk my daughter around the block.
3. Blood pressure is down (110/80). Reducing my changes for a stroke or other type of cardio condition.
4. No diabetes still.
5. I am still overweight, lost 10 lbs. though. I am motivated now to work on a 3 year weight balance plan...work in progress.
Your husband needs a reason to do it, if not for himself. I have a lot going on for me and I hope your husband sees a lot for him as well, enough to have him accept his predicament, do away with denial (he's responsible for himself) and find the motiviation/support to take his life to the next level.
Another fact to point out is that the 2nd cause of vehicle fatalities is drowsy driving. Not falling asleep at the wheel just simply being tired and driving. Your husband might not die in the crash but he could cause the death of another person. He might think he's doing fine sleeping the way he is, but is he willing to put someone else's life on the line because he's afraid of what the doctor might tell me?
Good luck getting your husband to see the doctor. As others have said, you can only do so much but it is up to him.
