Coffee.

The dictionary defintion for addiction is "the state of being enslaved to a habit or practice or to something that is psychologically or physically habit-forming, as narcotics, to such an extent that its cessation causes severe trauma." Now, I don't think my case goes as far to say it's a "trauma", nor is it narcotics. I am addicted to coffee! I love the smell of it, the taste of it, and I even love how the coffee mug warms up my hands on a cold day. Above all, coffee is my worst addiction.
