Yup, that's right--it's the ammonia in the blood that causes the encephalopathy. It's like trying to talk to someone with dementia. They can't remember anything, they get bizarre ideas--brrr!
TBS, I understand the heartbreak when they go back to drinking after they have experienced the miracle of life. All I can say is that alcohol is cunning, baffling and powerful. I know that over time, I finally accepted that he was not ready to quit drinking. At that point, we have our own choices to make. I chose not to put myself through that ordeal again. If he chose that path, it would be without my involvement. And that wasn't heartlessness on my part, it was a matter of self-preservation.
Some day I will probably hear that he has died of this disease. I will be sad, but I will not blame myself nor have any regrets. I am thankful I tried to help him, but when help is rejected then I have done what I could.
