I apologize if this sounds a bit self-serving, but I use Pacifica (http://thinkpacifica.com), an app that we are building, in order to track what affects my sleep. I've struggled with insomnia for a while so understanding how things like caffeine or lack of exercise affect it has been useful. And then I'll also use our progressive muscle relaxation exercise when trying to fall asleep. The irony is not lost on me that building a company around an anxiety app is also creating additional anxiety in my life...
