As I write this, I’m sitting at my desk with a hot cup of Earl Grey Tea secretly wishing I had coffee instead. I adore coffee! Ever since my University days, I have relied on Joe to give me a strong kick in the ass first thing in the morning and to fuel both my productivity and creativity at work. For years I had known that my consumption was on the higher side and that I should probably cut back. But a few weeks ago, I randomly Googled, how much caffeine can I have in a day? and discovered that the answer was way more complicated than I originally thought.
