Pepsi cola.
Oh and I always have to laugh at people who drink light soda (americans tend to call it diet soda though?) because they are on a diet to lose weight. Drinking light products or other special versions of a product due to an allergy or something is all good. But if you want to lose weight, don't drink soda, drink water or something like that...

Same for people who buy light/diet chips and such while they are at it and then wonder why they don't really lose any weight... :lol: Not to mention that most light products taste like crap.
