Thx for the advise, I will try it just as a one off, and see how it goes down, will surely let you know.
As it has ice, the carbonation wont be as a regular fizzy drink, as for the sugar content, I dont think I will be able to have much, so I think a one off sugar intake wont harm.
Thanks again for the advise, will post again to let you know how I get on. Wish me luck, lol.
