Rifaximin/xifaxin

Finally gt my gi doc to send me out a prescription for xifaxin. Any thoughts any worries? What should I expect on how on how feel? I had a neg sibo test few years bk despite all sibo symptoms and even had diverticulitis few times and he had me on low fodmap diet for about a year, bt who wants to keep losing wait dieting instead of taking care of the root cause lol?! Any herxing from sibo die off, I heard there was? Also was told to start my albendazole after the rifaximin, not at the same time,as it can be harsh on me.
