Hi Chris, welcome to the board, but so sorry you have to be here.
When the end was close for my mom she hardly ate and slept most of the time. The day she died she did wake up a bit more and tried to talk more but unfortunantely it she didn't make any sense and we couldn't make out what she was trying to tell us.
Here is a link that may help:
