I am new to this site. I've had crohn's for a few year's now. Am currently 26 years old. So frustrated, because I have c diff for the past week and a half. Had it about 6 months ago, and now it came back. Am taking flagyl for a week and its not doing anything. All out of ideas...so frustrated..Someone suggested drinking KEFIR (its a probiotic drink) Anyone ever tried it? How does it affect you? Will I be able to tolerate it now? PLease help... Any suggestions I will greatly appreciate it..
