I was diagnosed with sleep apnea about 16 months ago, so the experience is still very fresh in my mind. I did not start CPAP therapy until it was far too late to avoid losing my job.
For the previous couple years, my performance at work was falling off, and I was constantly flirting with burn-out. I was getting poor performance reviews and couldn't figure out why. I thought one of my problems was that my hearing was going, so I got fitted with hearing aids (I also suffer from mild hearing loss - more on that near the end of this story.)
My work performance improved slightly, but something else was going on. For some time, my wife had complained about my snoring. It was so bad that we were sleeping in separate rooms.
Sure, I was always tired, but I thought that was normal. It sneaks up on you. A parallel example would be that you can't specify a date when your eyesight got bad enough that you first needed glasses. You might be able to recall the date you got your first set of glasses though.
I had received as a gift an MP3 player that could also record 4 hours of sound in one take. About 2 years after receiving my hearing aids, I decided to record myself at night. That recording was extremely enlightening. Life changing enlightening. Based on that recording alone, I was convinced I had a breathing problem while trying to sleep. It was extremely uncomfortable listening to myself struggling to breath. If my wife had made such a recording years before, I would have acted in it then. Unfortunately, all she did was complain about it, and wake me up when I was snoring.
A week later I spent the night in a sleep lab and was diagnosed with sleep apnea. After another night in the lab, I had a prescription for a CPAP machine (Continuous Positive Airway Pressure, Pressure=8cm water). This is essentially a low pressure blower that (in my case) gently inflates my lungs without any effort on my part. I have to exhale against the pressure, but its less than blowing up a balloon. I find the experience relaxing. Humans are much stronger at exhaling than they are inhaling.
After a month of using the machine, I started feeling a lot better (you don't recover from the long term sleep debt in one night - 2 to 6 weeks seems to be common). For about the next week, I was really angry about how I had been treated at work (I suspect this is a common effect following treatment for a wide range of medical disorders such as waking from a coma.)
About that time, I lost my job due to poor performance. (The performance issues were real, but the reasons they cited for my release were bogus - they gave me a problem that could not be resolved within the framework I was allowed to work in.)
I wonder at the obituaries in the newspapers. The cause of death is often given as natural causes, but I suspect many are really breathing issues related to snoring.
After starting CPAP therapy, I found that perhaps 5-10% of the people about me use CPAPs, and found about others second hand. Two people I know have started CPAP therapy in the last year. CPAP machines may be much more common than the general population is aware.
I'll likely continue using the CPAP for the rest of my life. Surgical options don't always work, can not be undone, and are often not permanent anyway. CPAP therapy always works, and can be easily adjusted.
I still wear hearing aids, but I find that I don't need them all the time like I used to. The hearing loss is real. I frequently wear them turned off (the sound of my own typing drives me up the wall) and turn them on when needed. I suspect my brain is still recovering from years of sleep apnea, but it is improving.
