I have managed to kill my soda desires pretty good! I went from regular to diet about 2 years ago.. and lately trying to cut them out nearly 100%. What has worked GREAT for me is simply leaving the soda out, and letting it be warm. As I slowly have warmer and warmer soda it tastes worse and worse. Ive done it enough that really the idea of coke or pepsi doesnt give me the cold crisp refreshing cola taste, but I immediately think of the semi-gross, tasteless warm soda.
Not the most appealing thing in the world, but I dont drink soda anymore
