DH and I agreed we both need to as we seem to be sensitive to it.
So far we've worked out that Butterkist microwave sweet popcorn has sucralose in it, whereas the ready popped stuff is fine (annoying as it's more expensive)
Also some Soda Stream syrups (Dr Pete and Apple do, not sure of any others except that Cream Soda doesn't)
Anyone know anything else that contains it? It'd be good to put a list together, as when I google it all comes up with American groceries.
