Auto-Brewery Syndrome

    Case studies
    In 2004, a 44-year-old male was treated with the antibiotics clavulanic acid and amoxicillin for an unrelated condition. Eight days after being discharged, he returned to the emergency room with abdominal pain and belching and was in a state of confusion. An esophagogastroscopy showed the presence of S. cerevisiae and C. albicans in his gastric fluid, causing endogenous ethanol production.

I've been taking these medications lately, thanks for the paranoia!
