I'm a 39yr. old woman who has been vomiting and having diarehha for the last 2 wks. Everytime i eat it comes out one end or the other. I haven't really been able to eat but am hungry. I'm freezing and sometimes cold to the touch. I'm lethargic and want to sleep all the time. I called my DR. and was told to just drink plenty of fluids and take tylenol. i want to feel better but i don't know what to do.
