How old are you? Only, until a few years ago, I was on your side. Pointless nonsense, I thought. Then I got into my 50's and discovered that caffeinated coffee keeps me awake at night. *Then* I started getting gastritis, and discovered that caffeine and alcohol both aggravate it. All of a sudden decaff coffee doesn't seem so silly. Although I drink the real stuff in the mornings. (And indeed, I've just had an espresso and am halfway through a large mug of proper percolated.)
