I’ve never met a casual (occasional) Diet Coke drinker; they’re all die-hard addicts. How do I know? They show up at the office in the morning with their giant quick-mart cup, have bulk stashes under their office desk, and/or it’s the first thing they reach for in the morning when they get out of bed. In the morning, my Diet Coke Addict goes straight from bed to fridge and “pop” goes the Diet Coke can - the first of at least six for the day (who can keep count?). What is in that stuff and why are they so hooked? How do you even wean one off it?
