Hey Kathleen, I've seen that you've been telling alot of people about TMAU and how it could cause FBO, I believe that you said TMAU is more of a body odor and can be emitted through your sweat glans. But for me the smell I constantly am smelling is definitely coming form my anus. I know for a fact. It comes in small wiffs, and always smells exactly how my farts would smell. It's almost like I will know beforehand what my fart will smell like. I've also read about how you have told people that if they think the smell is coming from excessive gas they could take pepto bismol. I would try this but I have IBS-C and I think this could makes matters worse since I have heard Pepto can worsen constipation. So my question is, would you know any other alternatives I can try to stop this horrible smell from coming out of my anus? Thanks in advance for your time
