I remember seeing coca-cola life for a brief period at the norwegian supermarkets. I tried it once and it seemed similar to other small cola brands that use stevia. Tøyen cola is very tasty but cant be found everywhere, also i don't remember if it is made with sugar or not.
In the end i choose not to drink sodas at all as i consider them extremely unhealthy. Some studies have shown or implied that stevia can also have its own adverse health effects.
