@dp1733 I've had 4 bouts of Cdiff since May. I also took Vancomycin for 10 days after my second relapse. I took Flagyl for the first episode and within 5 days after completing it, Cdiff returned. After 5 days on Vanco, it returned. With this being your first episode, you may have good results with Vancomycin. I after my third bout of Cdiff, I did the Vanco pulse and taper and took it for 5 or 6 weeks. I was great for 3 weeks, but then Cdiff returned for a 4th time. I've now completed 10 days on Dificid and I'm two weeks out. They say with every episode, your chances increase greatly that you will have another one. Since I've had 4 now, I've decided that a fecal transplant will be next if the Dificid doesn't kill all the Cdiff spores. Like you, I went for quite some time with my first bout of Cdiff. I thought it was the flu and then e-coli since the romaine lettuce outbreak was going on at the same time in April. I finally tested positive for Cdiff after a doctors visit and mentioning that I had just finished taking 2 weeks of Clindamycin for a sinus infection. It's interesting that you don't know where you contacted it. Have you visited a nursing home or hospital in recent weeks?
