When drinking apple cider vinegar, side effects might be the last thing on your mind. After all, it’s just vinegar! However, aside from the aforementioned tooth enamel damage you could experience if you regularly drink it undiluted, large amounts of apple cider vinegar could cause nausea and indigestion in some people.8
