@mtborz I am sorry to hear about your husband's suffering and yours as well. I had nasopharyngeal carcinoma and I had also the feeding tube for almost 4 months. I think you need to make sure his mouth and throat have optimal hygiene. Maybe he is having difficulties because of an fungal infection or so. So alcohol free mouth wash with biotin are necessary. The PEG tube allows the patient to take shakes like Ensure. But if he still can swallow why the tube? It is important that he keeps swallowing liquids and soft food if he can because the muscles need to be trained to do their job. A speech therapist should be able to help him make some exercises that can help him swallow. He can do a barium swallow to check what's going on. I used to prepare a mouth at home and take it at least 8 times per day. 1 liter of water+ 1 big spoon of sodium carbonates+ 3 spoons of salt. I used to eat soups rich in protein and antioxidants, drink carrot and tomato juice, etc. Bit by bit he will be able to eat normally with one inconvenient which is mouth and throat dryness. So he needs to drink a lot of water.
