I know that PATM is somehow linked to smell because I do smell foul after like 3-4 hours after washing my mouth. And when I first contracted this disease six years ago, I smelled terrible. How do I know? I literally got comments from people who sat beside me. This was especially true when I was in stress. I started being obsessed with hygiene and after a while, People stopped complaining about the smell when my PATM activates, even when stressed, but they still cough and complain about itching in throat, chest, and nose. Just without the scent this time. So even though I believe smell is linked, I think the primary cause of PATM isn't smell.
I just learned that overusing your oil diffuser is actually bad for patm so use it maybe like once or twice a week im not sure. Also dont diffuse too much oil either because thats also bad.
