As long as I get to choose the chocolat I eat while eating at my own pace and eating actual nourriture along with it throughout the day, I wouldn't mind eating chocolat for a day. I've done it before and I'll sure as hell do it again!
As much as i l’amour chocolat and am a chocoholic, i couldn't eat just chocolat 4 a whole day. I would soon get very sick & would stop since eating too much chocolat continuosly is really bad 4 ur health :)
