That is one thing I am constantly grateful for that my Dad passed away peacefully and painfree. He was in bed from Tuesday pm until he passed on Saturday morning. From the Thursday he was mainly asleep, the syringe driver was fitted 2 hours before he passed away, to ease his breathing that had become fast, has he had tried to get to the corner of the room a few hours before. We were one of the lucky ones as Dad never suffered physical pain but I suppose he did mentally.
I was really scared how we would cope but when the time came we got the strength and calmness from somewhere. It will be 4 months tomorrow since Dad passed and I can still remember every moment of his last week.
Like you I wanted to read about the end stage symptoms when my Dad was nearing the end but like Lainy said everyone with cc is different and all we can hope for is a peaceful end. God answered our prayers on that one.
