I've taken abx many times. First time Zithro in 2010 or so. Almost complete remission (mild-moderate at the time) for less than a week, then symptoms crept back. Then tried Zithro again for longer - much less help but still worked to a degree until digestive side effects were too much. Then did Doxy on and off. Then a few years later Zithro again. Then TInidazole. Nothing recaptured that first experience, though.
I am very sorry to hear that! I was and still am experiencing some gastrointestinal side effects but luckily nothing so bad, that I had to stop prematurely.
I hope that you soon find something which helps you or that the research is making a huge step towards finding something which might at least put you into remission.
