hi there same sufferer. my breath also smells like faint garbage i couldn't smell this garbage smell cause i had sinus issues which inturn added to worse bb ever. after a visit to ent i was diagnosed with allergy to dust pollen i.e allergice rhinitis and given nasal irrigation with sodium bicarbonate... since then my nose is clear and most of bb but then i can really smell that faint garbage which i couldnt because of the blocked sinuses. did u find a cure to your bb ? i think our issues are similar. thanks
