I also was cured from fecal bad breath. I suffered for almost ten years from this dammed disease. The cause of my fecal breath was H. Pylori but i also suffered from Atrophic Rhinitis. Atrophic Rhinitis makes you smell like rotting flesh.
I did two Antibiotic sessions, one for H. Pylori and one for Atrophic Rhinitis...
I did a blog with all the information i could gather throughout all these years. Check it out and cure yourself. Hugs.
