Debilitating nausea & vomitting

AKMama • I'm a Mama Bear w/3 very active Cubs + 1 on the way. Our home is never as clean as I'd like, but it's filled w/love!
All. Night. Long.
3 previous pregnancies and never experienced anything like this. Misery.
Also, doc was going to call in an rx for Zofran, until I did some light reading on the birth defects. No thank you! 
What anti-nausea's are you ladies on?
