I was surprised at how easily I kicked my soda habit. I used to have at least 1 can or bottle of pepsi, dr. pepper, or cherry coke daily. I weened myself off of them by simply not buying them. This year I haven't really been wanting any. The fact that soda, diet or otherwise, is man-made and lacking in nutrition is enough to figure it's not beneficial even if our bodies can tolerate it. Since I heard that thirst is for water and hunger is for nutrients I haven't seen much point in drinking soda anymore.
