I was a Coca Cola addict myself. I have tried to quit many times. It is difficult, but not impossible! Right after my 41st birthday (which was just a few weeks ago) I decided that was it and I kicked the habit (hopefully for the last time). The first week was very hard, after that it has gotten easier. One difference this time is that I cut out all carbonated and caffeinated beverages which helped cut the craving. I now drink water throughout the day. As I finish one bottle, I start on another. Crystal Light is a favorite of mine too. I'll have one at lunch to add a little flavor to my water.
