CF Patient's Fast Food Reaction - In-N-Out,

Approx 20 after eating two cheese burgers without onions my daughter started having severe cramping and then about as we continued driving home to Campbell, Ca. She threw up several times. This along with diarrhea lasted all night until approx 10-11am the next morning.
I called her MD to verify there was no Flu's going around. I was very concerned as she has Cystic Fibrosis and was unable to take her medication and keep it down. Because of the continuing vomiting. | Symptoms: Diarrhea, Nausea, Vomiting, Cramps
