Have been to see Mom today and although she is normally a bit sleepy, today she was going into a very deep sleep whilst we were with her. I take her a yoghurt as she is losing weight and we are trying to build her up, and she just fell asleep during having the yoghurt. Just a bit worrying how deep she was asleep within a few minutes. It took quite a bit to wake her up and she could not keep her eyes open. I asked if she had had a bad night and they said she had slept quite well. Has anyone else experienced this in the late stages of this awful disease?
