Had Cdiff for over one year back in 2011 I was in the hospital for 4 months and was very sick where I almost died. I went all that time up until July of this year I think it was with out having even a tad bit of the runs and then I took keflex for a cut on my head that wasn't a big deal. They sewed it up and it really didn't need an antibiotic. Then a couple days later there it was like a bad habit.
