gastroenteritis
"I have used Zofran on two different occasions.  Went to the Dr for assistance after a week of vomiting because I was so miserable and weak. Felt so much better within 30 minutes I started eating the first thing I saw.  Second time I used it to bypass the stomach flu that everyone was catching.  I took it within 2 hours of symptoms; I fell asleep shaking, heart racing, with a fever and cold sweat, clutching a bucket to throw up in. Woke up 6 hours later feeling absolutely fine, just a little hungry."
