I had a similar experience with my cocoa demon, as I Iiked to call her.  My preference was the darker stuff.  It got to the point where I was forging documents and writing fake articles about recent studies finding chocolate to be beneficial for canine vision.  We had a blind dog.  I'd insert the leaflets into Veterinary Research Magazine, and leave them on the coffee table for my wife to read. I'd do it routinely, hoping to find some more chocolate in the cupboards.  I didn't have time to feel what a coward I was; I was too busy trying to savor it.
