Hospice & Other Help for the Dying

I've had a passion for easing the suffering of a human who only has days to live.  Without training I have no idea what would ease their suffering.  Or, with all the morphine, are they suffering?  I've seen Hospice in action a couple of times and I hold those workers in very high regard.  Do you have any experience with Hospice or other ways to make a dying person more comfortable?
