Bloesch, some of us (like me) simply have to stay on antibiotics all the time. Before you do that, I’d suggest seeing if everything short of that might be sufficient. If I were in your shoes, I’d try a maximal dose of a strong probiotic (e.g. Visbiome Extra Strength, 4 packets per day) plus a course of Cipro + Flagyl. I’d stay on that probiotic dose as long as you can, but it does get very expensive. Good luck!
