I knew I was in trouble when I started getting that 5th can of Diet Coke from the vending machine. Last week I was staring at the pile of cans on my desk thinking, not for the first time, that maybe I shouldn't be drinking this much diet coke. Now I'm sitting at my desk alternately sipping on this coffee and bottle of water and I'm thinking about Diet Coke. I need something else to drink. Maybe I should just keep drinking this water until the craving for Diet Coke goes away. The funny thing is the first time I tried Diet Coke, when kicking my regular non-diet soda habit, I hated it. . .
