my mother had c-diff and was treated once in the hospital. came home and need flagyl and probiotics 2 more times. she started losing weight so I wanted to take her to the hospital, she refused so her doctor put her on hospice. I stayed home with her. they gave her everything she needed, the day she died she sounded like she was drowning so I put her on her side. There was about 2 cups of a black cream consistency draining from her mouth in a three minutes time. what was it. There was no smell it was black as tar
