I’ve also been there and done that with my Mother two years ago.
The toughest part for me was removing food.
He wasn’t hungry and was just trying to eat for the family to show he was strong. They would bring his tray and he would play with the food for a half hour, salting it, twirling it and perhaps taking one bite that would be painfully swallowed and vomited back up within the hour.
I finally told the staff not to bring food unless he requested it. He never did, because he wasn’t hungry.
