congratulations on your pregnancy!!
I hope for your sake the nausea settles down soon, usually it does after 12wekks unless youre lke me and suffer until after 20wks!!! I had hyperemisis though (extreme ms) and after being hospitalised and placed on a drip for rehydration I was given some ZOFRAN tablets from the docs in emergency, they were a lifesaver for me, I was able to get a script from the gp, they are not cheap as they are the anti nausea drugs given to cancer patients but from what I was told (by the pharmacist who was also my boss) was that they were safer than maxolon or stemetil.
fruit tingles are another odd thing that helped too, as well as chocolate, there was one girl in my belly buddies who would have one square before she got out of bed, she swore by it! sounded good to me!!
