zero coke vs diet coke?

Neither diet coke or zero coke contain any sugar, although both are high on caffeine. Coke Zero is supposed to be a better approximation of the original coke, whilst diet coke is a re-branding of the eighties drink Tab, an early diet drink containing sacharin, renamed diet coke when the sacharin was replaced by aspartame.

Both are horrid! I prefer pepsi maxx, "thought of the day...did you know diet coke has more caffeine in than ordinary coca cola"... It shocked me!

I don't think there is very much difference and I wouldn't recommend drinking either often as they are extremely high in sugar and contain special chemicals to 'hold it down' other wise you would vomit because there is that much sugar.
