I love Sainsbury's products but this one dissappointed me very much. When I was eating it after the 3rd piece I got a very bad throat irritation despite having no alergies to food whatsoever. In a minute the irritation became so strong I lost the breath. I thought I am going to die. Thanks god I had some water in the room. There was a feeling inside my throat as if I've eaten some soup. I swear, beware of this product as it's something strange with this product's ingridients. It must be something wrong with it, I am 24 yrs healthy person with a strong imunne system and I have never had such thing happened to me (I am not allergic to cow's milk or gluten). Now I am very worried about it. What if all Sainsbury's products' descriptions do not say the whole truth about them. I would really suggest someone to check the chemical ingredients, it must be something strange in there. Very dissapointing. Never had a similar thing with dark chocolate of Sainsburys happened. I have bought 2 packs but thinking of going to the store and giving it back What if that stuff goes to a small child? dangerous stuff
