I’ve worked with good developers that drank coffee, and others that didn’t. I’ve not seen a trend one way or the other. Personally, I stopped drinking coffee for around 9mos while wrestling with insomnia. The insomnia I knew was stress related, but I assumed caffeine was a significant factor based on anecdotes like many of those found here. Diet, exercise, and teaching myself to better deal with stress seemed to take care of the insomnia (which lasted well after I stopped drinking coffee.) I didn’t notice any change in problem solving, creativity, etc., and ultimately I went back to drinking it. Like others here, I enjoy the taste and the ritual. If anything, I saw a productivity boost when I started drinking it again. I drink less caffeinated coffee these days though. It turns out that a lot of caffeine can be bad for retinal health, so if you’re very near-sighted or far-sighted, definitely consider dialing the caffeine back a bit if you drink a lot.
