Zofran?

Kelsie
Guys, I'm unbearably sick. All the time. I've lost upwards of 15 lbs since being pregnant. 5 of which were in the last week. I feel miserable. I can't keep anything down. I called my doctor and I'm thinking she is going to suggest zofran since I've tried dietary changes, b6, and ginger already with no luck but zofran scares me. Anyone have any experience for this first time mom? :) thanks in advance.
