Did you know that when people did the Pepsi challenge, a very high number of people legitimately chose Pepsi? They put in every commercial, made sure everyone knew it, etc, but it still didn't convince anyone to buy Pepsi over Coke. Point of the story is, everyone likes Pepsi better, even you, so stop buying Coke.
Also, the only time I drink soda is in a gin press (half soda water, half Sprite). It's great for well gin because that way it covers the cheap taste, but isn't too sweet. Having that much straight soda makes me sick.
