I also took Vanco for 6 weeks then we tried another 6 weeks and flagyl together which cleared it up. We didn't have to do Dificid, they were also talking about a poop transplant. I read up on those and they aren't very safe alot of people die from those which totally scared me and I read that after the fact. Keflex is on my no list of antibiotics thats a supposed cdiff starter. I went over a year the first time and I cried for and hour when I found out I had it the second time cause no one told me it stays in your system so it was a surprise to me. I hope you feel better soon!!
