I hope you get some relief soon. I know it is a tough road to walk. I have read so many articles and watched many panel discussions about C Diff, it is different for everyone that's what makes it so difficult to control and to find something that works. That's why I stopped taking probiotics some can make it worse. Florastor is one of the good probiotics for C Diff. I have spent so much money on different ones that really don't do anything. Yogurt can help in some instances but it needs to make it into the GI tract. Most don't, that's another misconception.
Ask your doc about the fecal transplant. It is the only thing that did work for me. That's not to say, it can raise its ugly head at anytime. In fact, we were taking our grandchildren away for a week and my doc did give me a 10 day supply of Vanco, just in case. Prayers for you. 🙂
