How do you know they do? And perhaps Morphine is given for reasons other than as a pain-killer in this case.
She also receives pain medication for her menses...so she feels pain. If she was as brain dead as they keep trying to convince people, midol wouldn't be needed.
I read somewhere online, here on freep IIRC(relating to Terri's 'death procedures'), that morphine is given in case the starved person survives to the point of going into gran mal siezures, then they won't fight the siezure.
Can anyone confirm this?
Try Googling death by dehydration.
