"Though we hate to ruin a good bit of lore with the facts, the truth is that although Mormons have been advised by church leaders to avoid caffeinated beverages, this suggestion has not been passed down as official church doctrine to which all members in good standing must adhere (unlike, say, the admonitions against coffee, tea, tobacco and alcohol, which are church doctrine). Mormons can swill Coca-Cola, eschew it and all other caffeinated beverages, or indulge in the occasional Coke and still be considered churchgoers in good standing."
