Another option is to try LDN, low dose naltrexone which is what Dr Siebecker the SIBO specialist recommended to me last week, others on the SCD yahoo site are using for pouchitis-SIBO symptoms. You will need an RX, a place in FL I spoke with 2 days ago specializes in it, Skips RX www.skipspharmacy.com. My local integrated MD recommended it as well and that company.
