@tina1125 I finished the Deficid for my 4th bout of Cdiff just one month ago. It hit me the hardest of all four and I lost 10 pounds during the first two weeks with it. And unfortunately, the first week the test came back negative so I had to go for almost 2 weeks before the test was positive for Cdiff. But during the past month, I've put almost all the weight back on. I wish I could keep it off and take off another 30 or 40 pounds. I'm sorry to hear you continue to lose weight plus muscle tone. I wouldn't wish Cdiff on my worst enemy. And I've never paid so much attention to BM's. 🙂
