Am i addicted to caffeine?

Okay so really like brisk Iced tea, the first time i drank it i was like ewww. But we kept buying so i just kept drinking it. After awhile it became my fav drink if we had it ic ould drink the entire 2 liters by myself. Even witht he raberry brisk wich isnt even my favorte, Without my brisk i dont really like other drinks lke the crystal lite, or the diet sodas that contain no caffeine. Am i addicted?
