Most all of the information in this book is readily available with a simple Internet search. The writing about conditions does not include in-depth or even correct information. In fact, the book is a cursory level look at the problem and doesn't address several issues that are caused by or correctable with such devices as a CPAP machine. This is more an informational pamphlet, and not a very good one at that. The reason I know this is because I have recently consulted with a sleep specialist, completed two overnight sleep tests, and have begun to use a CPAP device. The author fails to mention the several benefits of the device - just within 30 days, from a 7% reduction of an enlarged heart (if your heart is enlarged) to improved blood sugar levels if you're diabetic, reduced sinus congestion, improved muscle tone of the diaphragm which will lower blood pressure, and many more. If you think you have sleep apnea my advice is to find a good medical doctor who specializes in sleep problems. I told my primary care doctor three years ago that I had apnea and he told me that I couldn't have it because "you're not fat." Fat is only one small factor in this disease. I have also told my cardiologist that I have apnea and he just looks the other way preferring to peddle pills for my borderline hypertension (high in the morning while in bed, normal five minutes later after sitting - a significant signal of apnea). Another doctor finally agreed to have me sleep tested and I'm sure that it was truly a life saving decision. When I return to my primary care doctor I will give him a piece of my mind because even physicians do not understand a great deal about this deadly disease.
Additionally CPAP devices have been improved significantly over the negative context in which the author commented on them. I don't believe that he even bothered to investigate these devices at all in their current form. Mine is comfortable and presents no problems at all during sleep. Oh yeah, kissing is a little rough.
