We have found diet cordial, or cordial at all difficult to get in the
USA and
Caribbean and many countires. It was quite available in
asia and 1/4 of the
price of
Australia.
Diet Tonic would be a difficult comodity!
And then you have your gas bottles.
One of the things about cruising is that at times we must live much more simply than we have been used to.
No diet tonic? Then drink what the
health conscious locals drink!
