Coca-cola is one of the most revolting drinks ever. Whereas Pepsi at least has a natural stimulant in it, Coke is just sugar, colouring and flavourings. It is sickly sweet, does nothing for ones mood, and gives one a horribly bloated stomach. The sweetness gives you a rapid sugar low making you feel tired and dull. Of course it is not the only one, but it is so annoying that the adverts for it hail it as something magical ( notably the Christmas adverts), that has the whole family entranced, and that young males can become he-men on drinking it, etc. It tastes pretty ghastly and leaves an unpleasant aftertaste in one’s mouth. Don’t give it to your children, it will rot their teeth and make them hyperactive!
Take my advice and stick to spring water or pure fruit juice if you are thirsty, you will feel better for it and do the planet a favour. Manufacturing soft drinks is not environmentally friendly!
