I don't call it bad breath cause no ones ever said my breath stinks it's more like a cloud that surrounds me that smells like someone passed gas. It happens maybe a few times a day. In class non stop. If you have bad breath I don't think it comes and goes that's why I'm confused. My diet is very very healthy. No processed foods. Barely any meat. I juice often. I stay away from dairy and eggs. I've been eating really healthy for like 2 months. I was trying to kill Candida on prescription meds. I'm now on Neomycin trying to kill possible bacterial infection in intestines. I take extra stregth probiotics from Ultimate Flora. Still this smell comes in class. That's why I'm thinking TMAU type 2. The only other thing I haven't checked is with an ENT to see if it's coming from throat, sinuses, breath, but it just doesn't make sense. I did used to get sinus infections all the time though with bad phlem. And I have braces right now and two crowns and two fillings otherwise my teeth are in good condition.
