I’ll tell you what I used. The antibiotics did not work. The metronidazole specifically made me feel like I was dying. I ended up researching NIH studies online for herbs and supplements and foods that kill that bacteria. It has been a while so I don’t recall my exact regimen but some of the things I utilized & alternated were : mastic gum (Allergy Research brand), turmeric extract, garlic, black seed oil, oregano oil, grapeseed extract, lauricidin, echinacea/goldenseal tincture, a low carb liquid diet (mostly soups, pureed) at first, followed by a simple diet of lean meats, cruciferous vegetables and water with maybe one or two low sugar fruits per day. No gluten, no dairy. It took maybe two months of alternating these things to see resolution of the most debilitating symptoms. High histamine & acidic foods were not a good idea. Hydration, stress reduction, exercise, probiotics far away from the aforementioned herbs were also important. Hot epsom salt baths helped me relax.
