Personally, if I had your symptoms, I would treat those before I even thought about
treating lyme. You can't expect to get any healing from meds or herbs if your GI system won't absorb them.
Taking meds or herbs would probably be wasting your money and your time.
I hope you have a doctor helping you with all of those.
I am sure you are probably well educated on SIBO, but I sure like this Dr.'s advice.
