I ran into a similar problem a few months ago when I was hit with really severe symptoms consistent with an ulcer. I'd been experimenting too much with various herbal anti-inflammatories. I learned from this experience that I can't take any of that stuff.
Anyway, I panicked because 1) I could never undergo an endoscopy given how sick I am and 2) I figured I would have to go off RS and other stuff (the only thing that's ever helped my ME). After a few days of judicious PPI use and not taking any pro/prebiotics for a week or so things seem to resolve themselves. It was really frightening, @Sasha, so I totally understand how you feel. Like you I kept thinking what am I going to take to kill H. pylori given what we know about antibiotic damage. I do think, though, if things had continued I would have taken a course of triple therapy to get rid of it because the damage from the bacteria could be worse on the whole than from a short course of abx. That's just my personal opinion.
I came across a study at the time showing that PPI + amoxicillin + berberine was more effective than PPI + amoxicillin + clarithromycin. Apparently the triple therapy fails quite often these days due to clarithromycin resistance. I am struggling to see how amoxicillin could work for anything these days (except killing vulnerable commensals) so perhaps berberine would be something to try. It could produce awful die-off symptoms, though, judging by comments on blogs so I don't know if it's worth it.
With regard to RS and OI improvement, you might consider switching to something that's not going to feed SIBO. Have you tried any other prebiotics? Recently I've had surprisingly good results for my autonomic symptoms including POTS from beet root extract. You can buy 100 capsules for 6 bucks on iHerb so it seems like a no-brainer to try.
