Really enjoyed your article Mike! I too must have the same DNA make-up. I love coffee but it doesn’t love me! I looked into why and would highly recommend reading the chapter dedicated to caffeine in Michael Pollen’s book ‘This is Your Mind on Plants’. It’s both fascinating and hilarious describing how the author quit caffeine, cold turkey, to write the book, saying that he couldn’t possibly describe the vehicle he’s driving in without first stopping, getting out, and taking a good look at the thing from the outside. It’s no wonder that caffeine withdrawal is included in The Diagnostic and Statistical Manual of Mental Disorders [the bible of psychiatric diagnoses] - Hope you’re surviving your coffee ‘break’.
