I don't think this had the desired effect for me (or maybe it did). When I have a coke, or other soft drink it's generally because I want the sugar and caffeine, for instance part way through a long drive or during a night out. Generally I drink water, tea and a little coffee. I don't really want to be eating/drinking any artificial sweeteners. I have a hunch that this is not good for you and adjusts your taste to wanting more sweet things, so I tend to avoid. Regular Coca Cola still tastes ok, but now all promotions tend to be on sweetened drinks. Drinks such as Irn Bru have been ruined, as there is now no full sugar version available.
