Every normal person has as much trouble getting up early. Those folks who get up at 5:30 without an alarm are genetic anomalies.

I always have a shower kit and change of clothes at work (even over winter, when I rarely bicycle). I get my lunch ready and fold up a shirt (and underwear and socks for the next commute) into my panniers the night before, and make sure my tires are pumped. I fill a water bottle and have it in the fridge. I set the coffee maker to turn on 10 minutes before I get up so I can get a cup in me before I go. After I read the paper and have some coffee, I toss my lunch in my bag, put some coffee in a thermal travel cup (it fits in a bottle cage) and go.
