The biggest change in my life from getting a ChargeHR was realizing that, after 5 years of having a child (and then children) in my daily life, I was wayyyy more sleep-deprived than I realized. The newborn phase was obvious -- you're having to get up every couple hours and getting back to having a "full" night's sleep feels really awesome. But it turns out I _never_ got back to a full night's sleep, because having kids means I wake up earlier than I used to and the result is that I was constantly getting about 30 minutes less sleep than I really needed. I made a change to when I go to bed, and after 4 or 5 days of really getting a lot of sleep it was like going from a foggy day to sunshine in my mind.

(full disclosure: I now work for Fitbit!)

32 years old, only recently made the connection between poor moods and mental acuity and a series of nights with less than 8 hours sleep. :/

8 hours sleep seems like bliss to me. Even if I actually get to bed giving me enough time to have 8 hours sleep, I usually have trouble drifting off and then when I do, I'll wake a few hours later, and repeat.

I find that there is so much stimulation throughout the day, so many things I want to read about, experiment with and work related problems to solve, I really struggle to switch off at the end of the day. I try to console myself with this - http://www.wsj.com/articles/sleep-experts-close-in-on-the-op... 7 hours is better than 8 :-)
