Murphy, congratulations on completing your treatments! As said, gaining two pounds, and getting out, is a step in the right direction. Like you, I couldn't do 6 cans of Ensure or Glucerna or at least want too.
Other than what was already said, I found egg drop soup to be nutritious and tolerable, and basically lived on that, along with the supplemental drinks, scrambled eggs, cooked with lots of butter on low heat or other means to avoid any browning, and pastina cooked with chicken broth, lots of butter, and grated cheese, if it's tolerable. Slowly, I added or tasted different foods, sometimes as little as a teaspoon to help get my taste back on track, and it did, but it's not overnight. Even to this day, when I order out, it's not one dish, but may be as many as 5 or even 7 to see what I can eat and taste. Some even go to a buffet, which may be a cheaper way, but I'm selective with that.
Treating and preventing mucoctis and thrush helps too, as do avoiding spicy, acidic, too temperature hot, and sharp textured foods.
To increase appetite, caffeine helps, so does fat and sugar type foods, took marinol for a while also, which increases appetite. There are others as well.
