Wow!
I was never on a feeding tube (probably should have been), but was ordered by everyone to chug down 2000 calories/day by drinking Ensure. I could not handle the taste, nor could I understand how those ingredients were actually good for me. I set out to build my own drinks and base it on quality of calories. If I need to consume x calories, they may as well each mean something.
Stay healthy, you are inspiring to everyone that comes in contact with you.
All the best,
