It really works!
I have never been a morning person, and considering a medical sleep study cost $700-$1000 - I figured this was worth a try.  I'm not sure how, but it really works.  If I get up when the watch wakes me, I am well rested and focused.  Of course, if I turn off the alarm and go back to sleep, then it's my own fault when I'm sluggish.<br /><br />I have been able to determine the best length of sleep time for me (6-7 hours), and I am still working on disciplining myself to go to bed/wake up accordingly.<br /><br />My only complaint/concern is that the uploaded charts can be hard to understand, and their technical support is hard to get a hold of.  I was having an issue with my historical information getting skewed when I would upload new data, and it took about a month with several emails back and forth to be told that the software upload was in place.<br /><br />Overall, worth the investment! :)
