@mostlybill, I am a transplant recipient, and I want to Welcome you to Mayo Connect. When I joined Connect, I was Seeking support and answers for the same questions as you have named. I have discovered that all transplants, any organ, share these same concerns.
Mostlybill, I want ask a couple of questions to get this conversation aimed toward your concerns, Feel free to answer only as you feel comfortable to share here - How long ago did you receive your liver transplant? And how are you doing now? What is your number one question/ concern/ comment?
I am looking forward to hearing from you.

@mostlybill @tgshomes I too welcome both of you to Connect.
Bill, how do you feel that you are not the same person? I found the biggest difference for me was a huge amount of gratitude and appreciation of virtually everything. I don’t think those differences really define me though so I have not had a difficult time. My transplant was in September 2016.

@tgshomes your parents are very fortunate that you are so concerned and want to be able to understand better what they both are going through. The “mind cloudy-ness” that you refer to is of course hepatic encephalopathy, or HE. It varies a lot from person to person, mine was not present always but rather in episodes during which I was irrational and sometimes somewhat confrontational. When I saw a hepatologist she put me on xifaxan and I had no HE for almost a year. When they resumed it was assumed it was because my liver had deteriorated further and I had to start taking lactulose also. When I did not an HE episode I could live my normal life. My episodes were sometimes brief and going to bed for a while would cure them, but the worse ones put me in the hospital for two or three days.
Please feel free to ask anything and if it’s something that I or someone else has dealt with we are glad to explain.
JK
