Dear Middlechild,
Welcome to the forum. I’m a middlechild myself. I’ve lost my Father to cirrhosis, but I wasn’t there when he died. He continued to drink right to the very end. My brother’s were there and they said aside from the swelling from the ascites, he wasn’t complaining. He was singing as well, “I did it my way . . .”
You Father is so fortunate to have lived such a long life given the abuse he put upon himself. I assume hospice is involved? If so, they will see to it that he is not suffering. He would simply pass away peacefully.
I’m so sorry that you are having to go through this.
Penny
