Occasionally, I wouldn't eat a chocolate bar at all if I wasn't given one by my family at some weekends when sheffield united play at home (tradition, and I would feel bad if I rejected it). I also have chocolate at special occasions (birthday/christmas).
By far my favourite chocolate is the lindor lindtt (spelling?) balls.
EDIT: It may not be clear but I love chocolate, just it isn't good for you so shouldn't eat it too often.
