Obviously I wouldn't advise using all 49pp on chocolate but having some chocolate here and there I don't see a problem with... I get the galaxy ripple snacksize bars for 2pp. A fullsize is 5pp. A multipack cadbury flake is 4pp (normal size is 5pp). Oh and multipack twirls are 5pp (normal size are 6pp) so yeah you can have a choccie treat as long as you count it and keep it controlled
