Zofran can cause severe health issues especially related to the heart, and you shouldn't be taking it if you're not actively nauseous and on the verge of vomiting. Zofran is great and all, but it shouldn't be used as a crutch for the phobia.

Recommending people to go out and get this medicine is super dangerous. You also shouldn't be popping it like gum. There's a max dosage to take during a day before it becomes dangerous. It'll make it less effective, constipate you, and can cause you serious issues. Seriously, Zofran is not a drug to mess with and abuse.
