Jokes aside, as a person who consumes a lot of coffee, I have to admit that for me coffee is not a beverage to have on my own by the computer. It is an opportunity for a social encounter. I try to have my coffee breaks with other people. The coffee talk is a time to catch up on work AND non-work-related issues with my peers and friends.
There is research that shows that social-breaks boost productivity, and that the caffeine increases creativity. I am definitely addicted, not sure whether it is to the caffeine or to the social interactions. Whatever it is, it gives me a boost.
