Strawberry Fizzy

In my quest to give up diet soda, I've been trying to find substitutes that I like. Last week I made a pound cake with a simple syrup from our CSA strawberries to go on top (sugar, lemon juice, strawberries, basil). There was some strawberry topping left over, so I stirred it in with the carbonated water and it was pretty good! Not a Diet Coke, but pretty good. Going to keep looking for alternatives, but this was the best one so far.
