I live in Portland, Oregon, a veritable Mecca for the caffeinated sect. After my third cup today (I recently moved directly next door to one of the city's finest coffee shops?!) and quite a few months of feeling hopped up on the perfect brew, I think it's time to cool my jets. Do I quit cold turkey? Ease off with half decaf/half caf (then I'll be one of those annoying people, but whatever)? Please help dear readers — do you have any advice for kicking the coffee or caffeine habit?
