I don't have any personal experience with morphine,but the ratty,moody,not nice to be around I think we all experienced during the end of our using and certainly during w/ds.Addiction changes us into people that even we,ourselves don't care to be around,makes it hard to look into the mirror.During recovery we learn new coping skills and we find ourselves again.I know I have learned to like myself again and that makes me a much more pleasant person to be around....
