I drink flavored seltzer water and very rarely drink diet soda. You get your flavor and your fizz with none of the bad stuff!
Id rather have an occasional glass of the high test soda then diet everyday. However, if I were to drink diet soda it is usually Coke Zero or Cherry Coke Zero. To me it has the best flavor!
When I indulge in the real stuff, its almost always Sunkist! LOVE THAT STUFF!
