I am going to get one. I have all the symptoms of sleep apnea, I wake up with a dry mouth or nose and my wife often has to wake me up as I am snoring like a fog horn. I went to my Doctor and they got me rigged up for a sleep test with a load of sensors, but I could not fall asleep, the whole premise of 'i must sleep so the machine can record me, resulting in me not sleeping at all' and being told I had a negative test result.
