Corn Flour just does not work in this circumstance. My husband has had throat cancer, both vocal chords and top of voice box removed, and he needs a thickener like Nestle Restore Thickener or Karicare Aptamil Feed Thickener,or something similar, to be able to swallow any liquids without gagging, choking or coughing badly, to stop the liquid from going into his lungs. I need to know if I can buy such a product in Bali. Thank you.
