Hello I have been using CPAP successfully since 2004. It has made the world of difference in my life. I am more alert, sharper, and more productive since my diagnosis. I am very grateful to my primary care physician for being on the ball when I told him "I'm not this stupid", something is wrong with my brain. I was concerned that it was the beginning of something that would progressively get worse as I aged. Thankfully he asked the right questions, and had the suggestion of having a pulse oximetry test done. After those results showed a desaturation to 88% he suggested a polysomnography. Once I was diagnosed, I received my equipment fairly quickly, however my brain was quite fuzzy still and the explanations I received and the understanding that this was permanent for the rest of my life was a bit much to accept. It took 6 months for me to love my machine and equipment, and the difference in my life is substantial. I am grateful there is such a non invasive treatment that makes such a huge difference in my health.
