I think one reason I never got hooked on soda was that before aspartame, 0 calorie soda was disgusting. Also, back in my really strict calorie counting days, I once noticed that a can (12 oz) of soda had 150 calories. Since I knew that there weren't any nutrients, and I knew that a teaspoon of sugar had about 16 calories, it wasn't hard to see what soda really was - carbonated sugar water - and 9+ teaspoons of sugar to boot. It just seemed like a waste of my money.
