Ladies! Morning sickness blues!

I'm 7weeks and this morning sickness is terrible! This is my second pregnancy. I had morning sickness the whole nine months with my son! I was taking Zofran which helped me a little bit but now it has been known to cause birth defects so I'm definitely not taking it again! I have tried all types of ginger, B6, B12, bananas.. I feel like nothing is working. I'm just terrified I'm going to be sick again for another nine months with this one. Anyone have any other suggestions?
