I gave up coke/pepsi/irn bru/ginger beer etc, diet or not, a few months ago. Pretty much all my aches and pains have vanished (esp from the diet stuff) and if i decide to have a beer or twenty i no longer need an advil the next day once all that booze turns to sugar. Guess my bod just didn't like the stuff (i did though, i miss bru....my lunch for a can of bru....). Anyway....Pepsi is really quite syrupy though, coke is just more refreshing!
