I consider myself a functioning chocoholic.
I stick to dark chocolate and [almost] never eat it at work.
I tend to be a binge chocolate eater though, and once I open a pint of After Dark Chocolate frozen yogurt, I can't stop until there's none left.
I've been told that I'm in denial about my chocolate abuse, but really, I still have a job and can pay my bills, so I feel like it's under control.
