Did you ever get a chance to talk to your dad about the illness and the drugs effect on him personally? Did it take awhile to convince him to take it given his stoic nature?
No not really but he was aware of the beneficial effects of the drugs for his lungs, and for his rheumatoid arthritis. But near the end he was also on morphine to help his breathing which was great but it's a terrible drug for causing constipation!
His mind was clear up until the last two months because he was in the hospital and then palliative care. So that was not unexpected to be said since he'd never be home again.
It was quick really only about a month until he died once in palliative care. Although I could tell he was putting on a brave face. Dad died by my side in his sleep in palliative care but he was clear of mind two days before. He was never alone at home, in the hospital, or in palliative care I was always there.
Anyway I could ramble on about it more but really my family is lucky to live in a country with socialized medical system. I'm also thankful for drugs there are some amazingly helpful drugs can ease suffering of many people.
