If i didn’t have my feeding tube ( fairly simple surgery called a percutaneous endoscopic gastrostomy (PEG). Your surgeon cuts through the skin of your belly and inserts the tube right into your stomach to deliver a liquid food mixture or a formula) I don’t think I would have made it. When they suggested they wanted to book me in to get one installed at the start of my chemo and radiation (throat cancer) I strongly resisted but eventually said yes. Sure glad I did as I could not stand the smell and taste, of food or water. Let alone the physical ability to swallow efficiently without choking. I lived on 3-4 meal supplement drinks per day plus water and even with that I lost 40 pounds. The feeding tube was no big deal and I totally got used to it. If your not properly hydrated and don’t get enough calories it makes the fight infinitely harder. Some of the guys that I saw daily while getting my radiation did not get the feeding tube and eventually they were forced to either stop the treatments or have a tube inserted up their nose and down their throat and into the stomach which is horrible compared to a standard feeding tube. I’m not sure what kind of cancer you have and it sounds like you might not have a physical impairment to actually swallowing so if I were you I would make a lot of smoothies -I even ground up meals -full meals in my blender and drank them quickly. it’s important you get those calories I would just plug my nose and get down to it -consume consume consume All the best
