I found the hardest part about cutting out soda wasn't the caffeine withdrawl (which I expected), but I actually missed the carbonation and fizziness. If you find yourself in the same boat, go find Fruit Squeeze in your grocery store. It's fruit juice mixed with soda water, and no added sugars - according to the label, it's even worth a whole serving of fruit in the food pyramid.
The absolute best benefit of cutting out soda was economic. I can buy a gallon of filtered water from my grocery store for $0.29. A gallon of Diet Dr. Pepper would probably cost between four and six dollars.
