I am taking care of my 96 year old Copd Mother.  She  has been having so
 much flem lately.  Hospice says to take mucinex and they ordered their 
own form of Guaifenesin for her.  They also want me to increase her 
Morphine to pills.  I have not done this because I think Hospice is on a
 death mission but I need some advise on getting rid of her flem.  I 
just told her to gargle with salt water and I probably need to cut our 
her icecream. Help!
