I don't want to sound judgemental but have you talked to your doc? It sounds like a gasto situation like IBS or something. I know they said that COQ10 is suppose to help with odors but activated charcoal will definitely help with fecal order because it removes toxins like gas and other stuff from the stomach when taken on an empty stomach. If you decide to try the COQ10 just don't take so many at one time (especially if you are on any meds) I mean it will still go down just at different times.But I would definitely see a doc if you have not already, but you could maybe use some vinegar and water and even do enemas, to hold down the smell, until you see the doc, in the meantime.
