Fecal Microbiota(American Cancer Society)

The goal of this clinical trial is to study fecal microbiota transplantation(FMT) by oral capsule in people already diagnosed with auto-brewery syndrome (ABS, also known as gut fermentation syndrome). The main question it aims to answer: Is FMT safe and feasible in this syndrome?
Participants will
1. have a "gut cleanout" with oral antibiotics and a colon cleanse, similar to that administered before colonoscopy
2. receive five oral doses of fecal transplant capsules over a week
3. be followed for six months for safety and research samples
