It's weird-- sodas have changed so much in my lifetime. I used to love coca-cola. Then came the diet soda thing and sodas tasted like a chemistry experiment. Around the same time came New COke and then all sodas were either sweetened with high-fructose corn syrup (an absolute causative agent of "the beetus") and then most, if not all sodas, tasted too sweet. But not a good kind of sweet. Addictive, yeah, but good? I don't think so. I remember how amazing I used to think Dr. Pepper was; spicy and sort of with a raisin/prune sort of taste. Now, sadly, the only soda I truly like is Mexican Coca-Cola in the glass bottles. It tastes like I remember Coca-Cola tasting... Not overly sweet, but mildly peppery and complex.
I think I would throw-up if I tried to swig a can or bottle of Mountain Dew-- it is soooo sweet it's almost nauseating. Does Seltzer count as soda? I guess so-- I like that and mineral water!
