I am 10 1/2 weeks and have had the same problem since 5 weeks. I was in the hospital on Friday night to get IV because of dehydration. They put Zofran directly into my IV. I now take it every six hours. Did your doctor supply you with any? If nothing else works for you (as nothing did for me) you could try it. I feel sooooooo much better. Not perfect....but better.

It is horrible isn't it! Can't wait to feel better....and keeping you in my thoughts
