As a caregiver there are limits as to what we can do. Kevin got mad at me too and there were days that he would not eat, but he did realize that he was beginning to lose weight like crazy so he worked on finding things that worked. He got a peg, but hated it and, after trying it a couple times, refused.
If your husband doesn't get the mandatory intake, he will most likely end up in the hospital and that may be what it takes for him to come to his senses. They are grown men...we can only do so much for them. Dragging their butts to the hospital is one!
Good luck,
Kathy
