I saw on this site the other day about flavoured water from tesco or sainsburys that you can have in Cambridge because the flavours not acidic flavouring but I can't find the thread can anyone direct me to it please x
I'll just add my usual caveat that if you find drinking the stuff makes you a bit peckish, best not to carry on drinking it! But that's common sense, really.
What you're looking for are flavoured waters that don't have citric acid listed as one of the ingredients. Malic acid should be okay (note the 'should' )
