Yeah, I really recommend people giving up chocolate and sweets for a while then trying a Cadbury chocolate. It's really enough to make you sick. British chocolate is much sweeter than even American chocolate. We're just a bit immune because your tongue gets numb to all that sweetness.
Don't get me wrong, I think Cadbury is better than a lot of American mass produced chocolate. It's just not a culinary treasure or anything. *ducks* Never the less, I agree with people saying that it's likely that they won't change a thing with the formulas.
