Well I went to Aldi and managed to find the drinks. Bought the Cherry one (gorgeous) and the lime one...not had yet. they also had the pear one but I had already spotted a total seperate bottle of elderflower drink so bought that one instead....17p cheaper LOL.
I also found today in Asda Pear Drop, No Added Sugar Squash 2cal per 100ml and Sherbert Lemon Squash 1cal per 100ml....I remember the book or site saying that diet coke had to only be 1 cal per drink.....so I've used that as my guideline to buying this squash. Very yummy, the pear drop one smells divine.
Robinsons was a bit higher on the cals, so i won't buy that, but i think if its something thats been drunk since the begining your body doesn't know any different so it will work out for some people.
