so… as an avid drinker of diet soda, but someone who rarely finishes the entire 12 oz in one sitting, i have a question for you.
why the hell does diet cherry dr pepper go flat within half an hour of being opened, but diet cherry vanilla dr pepper stays fizzy for days in the fridge, much like root beer, ginger ale, orange, and cherry 7up? all of these are diet, if that matters.
im utterly baffled by this.
