I used to be addicted to fizzy drinks and cola in particular. Lately I was drinking it with great guilty as I worried about my teeth and healthy. One day I decided to buy Sainsbury's cola and I didn't see much difference in taste. I than noticed I wouldn't drink as much because the name and logo Coca-cola was absent. So far I've tried waitrose's cola and Asda's cola and they all go flat before I finished it and it is not to do with the taste but the brand psychological effect...
