I have four 120ml bottles of unopened Gaviscon Advance aniseed flavour if they are of use to anyone. I tried to offer them on Freegle but for some reason the post was not approved apparently they 'don't allow this type of thing'!
It's nice of you to offer but i would save yourself from possible issues. If someone was to have a bad reaction to the gaviscon then you could be found liable etc. although it seems a shame i would chuck them in the bin
