I'd like to meet the fool who drinks sugar water and thinks they are being healthy, anyway. Why not just drink a soda? I personally love Stevia and won't be bothered by a crowd of corn syrup junkies crying out because they aren't getting their fix.
They changed the entire formula not just the stevia addition... having said that... STEV is not going away... it's just not...
Also this will pave the way for a new stevia based drink to be introduced to the market and the customer base will switch from this to another product ;)
