No,, not at all. Anyhing that can be bought of the shelf should be rather than put more strain on the NHS.
But that's the point - the OP (as have I) found that it's not on the shelf.
Nobody wants to pay a prescription charge or buy a pre payment certificate, but when the shelves have been cleared of GF bread, GF flour, GF cereals, GF pasta, GF noodles, GF snacks, GF crackers, GF crisps, GF pizza bases, GF chicken, GF ham, GF Oats if they can be eaten at all, GF fish products, GF wraps, GF tortillas, GF brownies, GF cakes, GF sauces, GF curry pastes, GF soy sauce, GF gravy granules, GF everything except the biscuits because they're rank - perhaps going back on prescription would at least guarantee a small supply of the absolute basics of bread or flour.
