Have you talked to you medical team and your dietitian about your problems with swallowing? What did they suggest? Perhaps what is more pertinent is are you losing weight or how much weight have you lost from the beginning of treatment to now?

If the situation is worrisome, your medical team may be able to fit you with a nasal tube (NG) tube for feeding for now. A nurse can insert the tube and when you don't need it, you can even pull it out yourself. This is a temporary measure to ensure that you get enough nutrition while your swallowing slowly improves.

Do you keep track of how many calories you are taking in each day? If you throw it up, then it is not counted.

I'm afraid the swallowing difficulties will take a bit of time to resolve. Unfortunately, it is has quite a bit of impact on your quality of life. Hang in there, it will get better with time.
