Okay, decaf the least of the evils ;) but then again there are a lot of people who get headaches from decaf. The chemical to remove the caffeine is the responsible element in that.
And also, people do not realize that there is (relatively) very little caffeine in espresso based drinks. There is more caffeine in a cup of tea compared to an espresso. This in contrast to drip-coffees, which have a lot of caffeine.
Anyway, the sugar-free-not-fat-bla-bla (notice the decaf is gone Brady) is the very worst of it all.
