@sharonagnes, This is good news! I am happy that he is going to be referred to a transplant center. You will be amazed at the extensive amount of knowledge and information that will be available to you, as well as expert care for your husband.
I commend you and him for the success of his alcohol recovery. This will be something that is necessary before transplant listing.
I also hope that he gets an appointment soon and the the adjusted Lactulose dosages will lead to an improvement in the HE episodes.

My regional transplant center was only 45 minutes from our home. Is there a transplant center nearby? Do you know where he will be referred?
