Oh, I do love my Cpap machine! I've been using it faithfully for 3-4 years now and I sleep like the dead as soon as I turn it on. It was well worth the hassle of the sleep study and all the hoops to be jumped through for the insurance and all the out of pocket costs. I'm not too keen on housekeeping, but it's also worth the trouble of keeping the darn thing clean. I experienced the aforementioned insomnia, depression and high blood pressure, but also experienced memory loss to the point that I thought I was sliding into dementia! I couldn't function on many disturbing levels and the doctor even laughed (?!) and said I shouldn't even be driving. The Cpap machine turned that all around and I began feeling like a woman closer to my age, not like an 80 year old. My memory problems improved to the point that I was inspired to return to school and complete my degree.
