I'm sorry that you don't like to do the detoxing, but it will really help. Would you like me to list some sites that show you need to detox? I always wanted to see the articles myself, so if that's the case for you as well, I understand. If it makes you feel any better, I always disliked it as well.
Good move on getting away from the diet soda! That stuff is really, really unhealthy for a person.
