So I hate onions and thus, I don't eat them. But for like 2 weeks now I feel like I've eaten onions, when I haven't. My breath doesn't smell however. Also I brush my teeth and I feel like a taste of onions afterwards. I never eat onions because I hate the taste but what is going on? What can be the cause of me having this taste when I haven't eaten onions AND I don't smell like onions?
