Yes point taken re diet drinks, they can taste decidedly metallic. I'm sitting here drinking Coke Zero, considering it is supposedly sugar free, it tastes very good indeed. Give it a try.
Tizer without the apple. I'm afraid l have an absurdly sweet tooth, so guilty of drinking quite a lot of Coke/Pepsi, Fanta/Tango, Sprite, Tizer etc. over the years.
In fact it's only been in recent times that l have weaned myself off the full fat versions for their diet equivalent. Goodness...
