Every time I try eliminating Diet Coke, I end up having a harder time with controlling what I eat (and my weight loss stalls and I even start gaining weight)...it's hard to explain. I guess I'm somewhat addicted to Diet Coke. If I don't have one a day, then I eat other things to try to take the place of it such that I end up way over my points/calorie count for the day. I'm just better off to allow myself one Diet Coke a day. Sometimes I don't have one, but for now, at least until I get to my desired weight, I'm going to keep drinking them. I had to weigh the odds of what was worse, for myself...losing weight or having Diet Coke. It's really my only vice right now.
Otherwise, I eat very healthy...I go to the farmer's market weekly (& get organic fruits and veggies), I don't eat hardly any processed foods at all, drink filtered water, don't use any beauty products (including shampoo's) with parabens in them, include as many super foods as possible, exercise on a regular basis, etc.
