For those out there that don't like drinking plain water but need to keep the fluid balance topped up Morrisons do a wondereful line of sugar free squashes in exciting new flavours that all turn out to be syn free, they do a marshmallow one along with a sherbert lemon one and also a raspberry ripple one. The marshmallow one is a delight made up and then chilled for a couple of hours in the fridge, mmmmmmmm. I have also turned them into lollies in the freezer and these are obviously also syn free they are 69p a bottle or 2 for a £1. You get a litre in each bottle and as they are quite sweet they go a very long way indeed.
