I Think I Started With The Flu, Hot And Cold,

I think I started with the flu, hot and cold, vomitting/diarrhea. After 2 days, diaherria stopped, but this is the 4th day, I am still unable to keep any food or liquid down. I've zipped on Pedilite and chick soup broth, kept a little down, but most seems to come up. I'm very weak.
Beaucase of teeth problems, I lived on IB's for 4-5 weeks and took alot of tums.
