Thank you so much for the reply! Yes, about 15 yrs ago I tested positive for Sibo and since then have had multiple rounds of antibiotics. I went for a 2nd opinion and had an endoscopy when some biopsies done and he concluded that I don’t have Sibo. So, I’m so darn confused. I have an appt with another dr in May. We’ll see what she says. Did you have the sulfur smell also?
