I know this is going to buried but wanted to share. 

I worked as an LPN in long term care for a few years. I had a patient with Multiple Sclerosis that was actively dying. We were dosing her with sublingual morphine every hour and it really wasn’t helping to calm or sedate her. She was also NPO (nothing by mouth) besides the liquid morphine because she had lost her gag reflex. 

She was begging for water but there was nothing to be done. 

The last time I dosed her with morphine she looked me in the eye and once again begged for water, voice grating from being so dry. I squirted the morphine into her mouth, and she gave me an accusing stare as she rasped “that wasn’t very much water. “ She died less than an hour later. It has haunted me since.
