I feel your pain. I to was put on clindamycin and contracted cdiff. I lost 22 pounds in 2 months was hospitalized over thanksgiving. I am on danactiv and havie been on vancomycin for a long time. I had in twice in two months. I too can not tell what to eat. Sometimes ok but meat seems to make it flare up. I was told about fecal transplant and I did research and have decided if not improving by January that is what I will do. Good luck to you.
