and SIBO is complicated to treat. I finished 2 rounds (one xifaxan, one herbal) and using pro-kinetics (LDN and Iberogast) but now believe it is coming back. Getting tested again soon. Next step, physical therapist using Wurn technique. Consult next week. Good luck and make sure to read ALL of the SIBO info on the website. There is also a good FB group, SIBO SOS II. Healing IS possible! The SIBO could have caused the Crohn's or vice versa, but treating mine made me much better. hugs
