I used to be addicted to Coke (had to be bottles/cans - no fountain drinks for me). 6-8 cans a day every day. We would shop at Sam's for my supply every week (and sometimes twice).
Also had coffee in the morning (iced or not). And iced tea when I couldn't get either one of those. You could say I was addicted to caffeine. Well, first coffee didn't taste good. Then, I tried MIOs. Made the water taste so much better! I finally stopped drinking Coke and switched to MIOs and iced tea. Still some caffeine but not nearly as much. And I'm saving at least 1000 calories a day...
A few days ago, though, I was feeling sick and asked my DH to bring home something carbonated. All they had was Mexican Coke. What's that, you may ask? Glass bottles with the old-fashioned top, made with real sugar. WOW! I now know what my splurge (bday, xmas, etc) drink is going to be. But since they're hard to find and kind of expensive, I luckily can't have them all the time.
I still like a "real" Coke every now and then, not diet. So even though its pricy, I keep those 6 packs of 8 oz mini cans and when I feel like one, its not as bad as full can or bottle.
