I used to drink Dr. Pepper constantly, and I was kinda overweight. I brought it down to about 1 can a day, then on New Years I just quit completely. For the first month or so I was just always thinking about drinking it but for the most part if I just drank a glass of water the urge would go away, because it's really more about thirst than taste.
Anyway I haven't drank any so far. I still drink coffee. I'm not Bones4. I opened the fridge this morning, and mysteriously found a can of Dr. Pepper sitting right in the door. Must resist.
