Oh wow, you are an RD! Sorry to hear that the low FODMAP diet didn't help - it's only helped me somewhat - it's definitely not perfect. Have you tried herbal antimicrobials at all for SIBO (like berberine)? I haven't yet, but I have heard they can be good - even as good as an antibiotic. I've tried CBD as well, but I didn't notice any difference unfortunately. If only someone would come up with a way to replace the ileocecal valve 🙁 !
