> That's surprising to me, considering that coffee is quite addictive.
I'm not sure that it really is. You can build a physical dependence to caffeine, but in my experience there's no mentally addictive component. For a period of time I drank a lot of coffee and then stopped cold turkey, and the only effect was a couple days of physical unpleasantness. I now limit my coffee consumption to a max of one cup per day, and have no issues switching between coffee/decaf/no coffee on any particular day or for any arbitrary period of time.
