I am not addicted to soda, but I do love to drink it often. I like many different kinds of soda and, like people pair wines with their food, I fancy myself a connoisseur of sodas, being able to pair the perfect one with different meals, settings, etc.
root beer (especially "Dad's" brand!) is basically the perfect soda for pizza. Sprite (or any lemon-lime soda) is a great match for pasta dishes. And some sodas are really just best by themselves, like Welchs Grape Soda, Mountain Dew, or my current favorite soda ... Wild Cherry Pepsi. Mmmm!
Sonic Happy Hour drink specials. Between 2-4pm every day their drinks and slushes are half-priced, which makes it very inexpensive to try many different combinations. I've become partial to Sprite with Watermelon flavoring added, but there are literally thousands of other possible combinations. Root Beer with Vanilla is good. My wife is partial to Dr. Pepper with Cherry and Vanilla added. Their Powerade Slush is very tasty too.
So what's your favorite soda? I'd love to hear and try it out myself some time!
