Is that the same as Aspartame? AKA Nutra-sweet? Most fizzy drinks have both saccarine and aspartame in them as well as suger, why don't you try diluting fruit juices with soda/sparlking spring water? Some fruit teas are very refreshing left cold and served with ice or a slice of lemon, and I know the health food shop does small cartons of drinks without colours or sweetners, but I don't theink they're fizzy. they might have something in cans though, you could always ask. You could also make/buy Innocent smoothies for a change.
