Will they give you enough morphine if you are at the end to keep you pain free?

Yes! I'm sorry that you have to ask that question, but yes, we should. If you're worried, ask for consult from hospice & palliative care specialist. Better yet, ask to see if you qualify for hospice benefits. If you do, we can then focus on caring for you (and your family) rather than on curing you when a cure isn't realistic.
