I've been using a CPAP for years, even posted a pic of myself on here somewhere. To Glatt's point, how can anyone tell if it's working? I
think it's working, but there are days when I feel exhausted from the get-go. Is that from the Apnea, or could there be something else going on? Who knows?
Interesting piece
"WHEN an earthquake of magnitude 6.0 struck Northern California on August 24th at 3.20am, it not only shook the ground—it also shook people awake. Strikingly, it is possible to identify the tremblor's epicentre by measuring the disrupted sleep suffered by thousands of people in the area who use a bracelet pedometer and sleep-tracking device made by Jawbone (see chart below). The company spotted trends in how long it took people to return to their slumber, and noted that 45% of people within 15 miles of the epicentre were unable to go back to sleep at all."
