Lately, I've been adding LOTS of ground cinnamon to my coffee for its purported health benefits. I'm not sure if the coffee/caffeine cancels out the cinnamon, but I feel it's, at least, an earnest attempt to upgrade my vice. I often start my day with a glass of Vietnamese iced coffee (aka cà phê sữa đá). Recently I added a sprig of mint and "slap my face!" The resulting flavor is a most winning combination.
Also, my days have been feeling like this. Whee!!!
