stinky breath anyone !???

i can’t be the only one who gets stinky breath while on vyvanse !? since vyvanse does obviously curve your appetite a lot .. and i have a bad relationship with food in all aspects i don’t eat much at all while on it and when you don’t eat you get “ hunger breath “ people say you can take away hunger breath by just drinking a lot of water but while on vyvanse water just tastes nasty to me and i just can’t drink a lot , so my mouth gets super dry like cotton mouth so i always carry gum and juice on me if i can because the only thing that helps my breath is juice really for some reason but i also have the same problem with the juice as i do with water .. send help pls !
