I have dumping syndrome, Sibo and irritable bowel. I have been taking anti biotics since 1980 none of which have worked. However I have been taking these for 7 days and the difference is amazing. I have been given one months supply. It was me that found the drug on the internet and my consultant prescribed them for me. However because of the cost I don't want to take more than needed, so I can hopefully keep having them. I live in UK but costing is still an issue
