mate, i feel for you. i have a similar problem where when i eat a specific food (i dunno what it is) and if i fart i literally make myself and sometimes people around me rush to the toilet to vomit from the smells, and after i vomit i get headaches from the intensity of the smell. sometimes when unexpected it can really fuck up your perfect day
but it only happens very rarely. maybe like 2 times a month. but its something to definately watch out for
