I don’t really drink fizzy drinks these days but one thing I will say is Coca Cola is addictive. I never really drank much of it but always quite liked it. Then a few places I worked in the U.K. used to just leave a load of cans of Coke in the canteen kitchen for whoever wanted them, so you’d be more inclined to grab one rather than just a cup of milk or water. Quick enough I found myself always picking up a can or bottle of it whenever I was in a shop. Changed jobs and continued to buy it a lot more than I had previously and it actually took a conscious effort to stop.
