It's not normal. But if she's anything like me, she's not "throwing up" like a normal person throws up. The food is not getting into her stomach. It's getting stuck in her esophogas (sic) which makes her feel pressure in her chest. So she goes into the bathroom, bends over the toilet and it just comes out. And then she probably goes back to eating. Correct me if I'm wrong. That's happening because she's over eating and she's eating the wrong foods - she's basically eating like she's normal with no restrictions. She needs to learn how to eat with a band. That's the hard part. She's not bulimic IMHO.
