From The People:
"It was extremely frightening. Your first thought is that it's a rejection - and if so, I'd have been in serious trouble.
"You get impatient in hospital but, in hindsight, I should have stayed there perhaps another week.
"Luckily, I was sensible enough to get straight back. When you've had a transplant, the little things actually become big things."
"I thought, 'I can't cope. Is it all worth it?' I'd never have done anything about it. I'd just break down sobbing for no reason. Alex came into the room once to find me crying my eyes out.
"It really worried her. It's never happened before, even when I was drinking. I felt I could do nothing for myself.
"I couldn't even put my socks on. If I dropped something, someone else had to pick it up.
"I didn't want to eat or get out of bed. I just started thinking, 'I'll lie here until I'm better'. Of course, I wouldn't have ended it because, eventually, I could see good would come out of it."
"When you know your doctors are the best in Britain and they're a bit bamboozled, it is a worry. It was a bit like a chess match at the hospital, deciding which move to make.
"One night I was given a drug through an intravenous drip which caused me the greatest pain I've known - it felt like I had knives in the base of my spine.
"I have never felt anything like it. I was screaming in pain. The poor nurse sitting with me had the shock of her life and stopped the drip straight away."
Eventually he was discharged for the third and, he hopes, final time.
He will need regular tests, and his diet and environment will have to be monitored all his life to avoid infection.
"Even today, we looked at each other and said we have a beautiful home and a beautiful life.
"It's the silly little things that mean so much, like getting out and feeding the fish, sitting together and looking at brochures for a holiday home in Malta or Portugal - or just going downstairs for a cup of tea.
"It's terrible when I think of some of the things I did and said when I was drunk. I was vicious."
Best added: "Now I want to make it all up to Alex and start trying for a family when I'm well enough."
