Kicking the Coke habit can happen but it isn't easy. Three months ago I made the decision to take care of my health and lower my chemical load. I was drinking about 3 L of Coke Zero a day. I quit cold turkey and the first week was very difficult. I can say that I don't really miss it anymore and I sleep much better now. I don't drink the Crystal Light because I find it's trading one chemical for another but I did switch to bottled spring water which I find tastes much better than tap. I think there's a lot of arguments on both sides of the fence on whether or not diet pop affects wL but I can definately say that I notice a big difference in how I feel since I traded the Coke for Water.
