nausea/vomiting
"I have severe nausea and vomiting due to an extreme case of endometriosis. I have to be hospitalized because of pain, weakness and dehydration because of severe vomiting. I can't even hold down a tiny sip of water for 2 mins. I have tried every medication possible and 
Zofran ODT is the only thing that gives me relief! It is a prescription I always have on hand at all times."
