The "right now" whereof I spoke is basically any crisis during a quickly progressing terminal cancer after the oxycontin starts and before the morphine.
When a person can speak, and change their mind, and everyone involved in care isn't present at a particular instant or on the same page with what to do.
If that clarifies.
I’ve witnessed two elderly people in my family with cancer in severe pain just ride a morphine drip waiting in anticipation for death. The only reason they didn’t euthanize is because it isn’t legal.
