Sleep score: 66My Withings sleep tracker awarded my a score of 66 for this night. Sleep score: 95I'd been looking forward to trying this one and as it has the most scientific backing, I gave it the toughest test. A second test on a regular work day had better results, with my overall sleep score leaping to 95. Sleep score: 68Nothing is ever going to beat a plain old brownie — but these were pretty good. My sleep score of 68 isn't bad for a Sunday night, either, although it did take me a while to fall asleep.
