I agree with latch. Eating well, getting exercise and sleeping well are the #1 contributors to my long-term productivity and effectiveness. I'm not saying you have to be a gym rat but some kind of routine (even a 30-60 minute walk) and regular non-junk meals will make you feel better, and as a result sleep better. The results are cumulative, and they will beat the pants off any task-driven coffee-fueled routine you develop for yourself while eating pizza at your desk at 3am. :-)
