I'm in the 11th week also and I had nausea and vomiting often . It got to the point where I had to go to the ER for fluids but I have been prescribed Zofran which works really well.
Have you tried Zofran? My first pregnancy I was sick for 6 months straight.. All I drank was milk and ate potatoes.. Nasty I know.. But I tried everything and anything to keep the nausea to a minimum..
