I wish I could help you , but were all struggling with this condition and we don't know how to cure ourselves let alone your husband. The best thing I can suggest to you is to look into the major remedies that cured different people of this odor. Like probiotics, magnesium, chlorophyll, chlorella, restrictive diets,zinc, and charcoal tablets. That's all that I can think of at this moment. Sorry for the late reply, but I hope this helps
