On Monday morning I found out that my hydrogen breath test was positive for small intestinal bacterial overgrowth. Today is my second day on 1200 mg of Xifaxan. I am also taking VSL #3. I am trying to keep my regular low-carb diet with minimal lactose. It’s going well. I don’t feel so great. Kind of like a good day pre-low-carb. A bit of gas, especially at the gym. Some pain. Lots of rumbling, but some of it from places that I’ve never really heard rumbling before. I will start my period soon, so the little bit of bloating could be that.
