First of all, let me say that Im sorry for you and your familys loss. It is never easy under any circumstances. Ive been there with my MIL and both my parents and other family members.
But then let me ask you a few honest questions. If your MIL was in excruciating and constant pain, would she have been at any point of having meaningfully communication with you? And was she in a nursing home or a hospice care facility? They are two very different things. I do not BTW have a very good opinion of most nursing homes from what Ive observed. My experiences with those Ive know in Catholic hospice care, both in a facility and with in home care, is vastly different than what I observed in commercial nursing homes.
As far as being addicted to pain meds, if a person is in their final days and hours of life, what difference does that really make if they are addicted? Its not as if a dying person in their very last days or hours of their life is going to suddenly get up out of their bed and hold up a pharmacy looking for drugs or hold you up at the ATM looking for cash to support their drug habit. The sad thing is that many people in chronic and debilitating pain are now being denied medication out of fear of addiction. While some people who are addicts and not in need of pain relief, their abuse of the system means that many who are in need of such meds are treated like addicts whether they are or arent.
Yes, they die in a stuperous, pain-free state, but is it right?
So what is the alternative? Withhold all pain meds from the terminally ill and dying? Would you really want that for someone you care about?
Unless one has experienced a loved one go through a very painful terminal illness, one really isn’t making an informed judgement. It might be easy to say don’t drug someone up until one sees their mom or dad writhing and screaming in pain that has no other hope, short of death, of ending. Pain can be so bad it makes one desire death. What do you do when a loved one is in so much pain they are beyond even that?
