I don't really see waking up early as a "life hack" that you need to train yourself to perform on regular basis. I simply activate my intergalactic ear plugs and make a general announcement (unfortunately I live with night owls) - good night everybody, the one to wake me up will be defenestrated and that's it. I'd rather be fully aware and productive at 5am than keep my brain up with infinite stream of coffee in the middle of a night.
