Only 18 days since my original post and he is gone. Those were the longest 18 days of my life. He was so swollen by the end he could no longer see. We all held his hand, talk to him but mostly we all just sat with him and listened to the Beatles it is amazing what music can do. I'm gratefull he is no longer suffering and I will miss him. Thank you all for your replies, unfortunately he didn't experience that surge of energy we were hoping for.
