Thanks guys, I'll pass on the kind words to my family.

He isn't a candidate for a transplant because he has been unable to stay clean for any length of time. In order to get on the list, he'd have to stay clean for at least 6 months, but given the severity of his condition, it's not likely that he'll make it that far. He's all swollen now, very, very yellow, when he talks it's a very robotic sounding speach. And he's only 6 years older than me.
