Morning Sickness and Zofran

I am about 7 weeks pregnant, and went to the Dr. this morning feeling dehydrated.  I was put on several IV drops with my son because of my morning sickness.  They wouldn't offer me any medication until I was into my 2nd trimester.  Today they said try Zofran (a class B drug, that is at the same level of saftey at Tylenol.)   My question is has anyone tried this before?  How did it work for you.  I have already lost 4 pounds (lost 11 with my son), so I am needing some relief.

Thanks
