I'm sure in typical Karlos fashion, you'll now break down the chemical composition of Mountain Dew but you miss the point. Until I started drinking diet drinks, I never really noticed what sodas tasted like, just that they were cold, wet, and bubbly. Now that I've discovered that I like the taste of diet sodas, regular sodas are all but undrinkable.
To see what I mean, over the course of two weeks drink nothing but Diet Coke. Don't stop drinking sodas, just drink diet instead. When you pick up your next non-diet soda, all you will taste is sickeningly sweet sugar and syrup.
Not actually a good taste really.
