I wish I could say more, Michael. I now know that Sinc was found unconscious in his home. As best anyone can tell, he'd been there 2-3 days (he lives alone and it was Thanksgiving week in the US). The doctors still think his liver was affected by a combination of medications he's been taking. It started producing ammonia that was released back into the body which clouded his brain...this probably explains why he hasn't been very active online for some time now. The liver is normally able to regenerate itself, but I guess it has been damaged to a point where it is either unable to do so or is doing it very slowly.
And due to his time with no food or water before he was found, his kidneys also started their shutdown mode. They appear to have returned to normal function, so we just need the liver to start doing it's thing again.
His sister posted on Facebook, so I guess I can say it here, that she and her sister (who both live here in CA) are going to be headed to CO "to say goodbye, just in case..".
