I don't know if it's the carbonation or the caffeine, but I am addicted to Coke/Diet Coke, whatever I can get my hands on. Is there anyone out there who has overcome this addiction? I seriously want to cut this out, but I have terrible headaches, am irritable, etc. when I try. Do I just stick it out until I don't crave it anymore? This sounds so silly when I actually type it out, but it is a real problem to me and I really want to stop. I know I'll feel better and I know I'll be setting a better example for my kids.
