As a diabetic, I only drink diet. Now since I have an insulin pump, I can drink regular soda, but I choose not to. Sugary soda destroys teeth. I've never had a cavity in my life so I'd like to keep it that way. Also I've gotten so used to drinking diet, I don't really care for regular soda. Once in a while I'll get some crazy mountain dew flavor, but I don't make a habit out of it.
