Your probably addicted to the caffeine in it, not the dr. pepper itself. Contrary to what some people may say, it is actually possible to become addicted to caffeine. I've kind of been there myself to a point. Obviously, it's not an "addiction" in the same sense as some type of hard core drug. However, it can get to the point where you feel like you have to have it and without you just feel tired, miserable, and are not able to function at your best. You may also find yourself with a headache if you stop drinking it. I used to drink a Monster or Nos once or twice a day along with Mountain Dew, and I can say that it definitely can become a habit even though it does very little other than make you feel jittery/sometimes more alert. It's also not good for your heart, especially if you start noticing palpitations. It's surprising since too much caffeine just makes you feel awful and hyper.
