The reason behind my coffee madness is: it helps cool it down to the temp I enjoy, provides a nice slosh factor while I'm driving or walking. I can honestly tell my Dr. that I've cut down on my caffeine intake. While three cups of coffee is normally 24 oz., in my world it's only 12 oz. Makes perfect sense to me. And I'm a slow coffee drinker, with a full cup by the time I get to the bottom half it's cooled down beyond drinkability.
