Thanks for sharing the information. I was wondering how you knew you needed Xifaxan? I believe I have SIBO, though gastro said no. I was going to do my own SIBO breath test, and I see Xifaxan is used a lot to remedy. Did you GI doc do a sibo test for you or something to know to prescribe? My 2nd bout of covid seems to have messed with my gut health a lot. Thanks for sharing.
