Thank you
@GomezAddams for the detailed medical information. I've experienced many of those run-around and shady shit proceedures.
My sleep study was not just for snoring... my wife would wake me up often because I would do that stop-breathing-snort-wake-myself-up stuff which was keeping her awake, making me feel like a freight train ran me over, etc. My sleep study they stopped me half way into the night because I stopped breathing so many times in an hour, it was off the top of their scale and my Oxygen levels were in the low 80's. Almost IMMEDIATELY started feeling better once I got used to using it. I use a Phillips nasal pillow because I couldn't sleep with a full mask.
I feel so much better in the mornings and sleep so much more soundly without keeping my wife awake. It was ruining our marriage before not to mention bothering guests who would sleep across the hall and could hear me.
My insurance at the time paid for all the testing but made me buy the machine $800. Instead of paying the inflated pricing when I needed new hoses and masks, I'd buy "samples" from our local Medical supply for a fraction of the price. Now Amazon has most of the pieces I need to replenish. I stopped using the water add on because it just got gross and I had a harder time cleaning it. As long as there's moisture in the house, I'm fine, or in the driest part of winter we'll run a humidifier in the room.
I started asking about how often the machine needed to be upgraded to ensure it's working right... the Doc wanted to sell me a $3000 CPAP or rent one to me for a couple hundred a month. No thanks.
Called the insurance concierge and got switched to different doc where I was able to buy a $900 machine and 50/50 with the insurance. That was great, but the medical supply I got it from calls me every goddamned month trying to sell me filters and hoses and shit that I don't need to replace. I keep everything clean and replace the pads and filters from Amazon.
The combination of CPAP, diagnosing my thyroid issue, and finally addressing my ADD meds have regulated my body to actually feeling good and healthy every day, I'm finally able to curb much of my weight gain from the past several years (down 15 lbs from Christmas, prob 15 to go) and I'm productive at work and home.
