Ladies that are sick please be aware of what you are taking by taking those combination medicines like Thera Flu, DayQuil, NyQuil, etc.... I had so many patients that would take those plus Tylenol, Mucinex, Antihitimines or whatever and were overdosing themselves. That is hard and dangerous on your body and with taking a lot of Tylenol you could have rebound headaches which is basically caused by Tylenol withdrawal. Hope y'all all get to feeling better quickly, remember to drink ALOT of good fluids, stay away from caffeine and eat something even if its crackers, not eating will make you more nauseous, your stomach makes acid every time you swallow
