I hope he's as comfortable as he can be Wolf.
This is a strange period in the process for you and your family. You're starting to shift from wanting him to get better, or to still be there for you, and starting to hope that he doesn't suffer much longer. It's hard to picture now, but you will feel relief after he passes. For him mostly, but it's ok to feel it for yourself too.
That's heavy, so I'll close with a funny study from my dad's last week or so.
The Alzheimer's was doing it's Alzheimer's thing, and there were large parts of his day where we could tell he either didn't know who we were or he couldn't really communicate it. (That's not the funny part, it's coming up)
His wife, best lifelong friend & wife, And my brothers and I were there at his bedside at hospice. We were busting each other's chops and laughing about something or another. My dad was laughing but he didn't really seem to be connecting, just laughing because everyone else was. So I looked at him and said "what are you laughing at? I got all the good looks...." then we could see the light switch on for him, and we knew he knew exactly who everyone was, and he was in on the joke. He looked me square in the eye and said "Awwww, fuck you....." With a big silly grin. Best laugh ever. He had never said that to me before, and it's hysterical that it's one of the last things he said to me. Totally busting my chops. We still get a laugh out of it.
Hang in there man.
