sorry hun, but in my experience, you have to just keep trying different things, and making sure that you don't get dehydrated ...

sleep was the only consistent thing which helped (and I mean helped - it was less intense if I slept LOTS - as in 12+ hours at night - but I would still have nausea and some vomiting).

other things which helped for a while and then didn't:-

* watermelon
* mineral water with a quirt of lime juice
* just letting myself have a big spew in the morning, and then getting on with life ...
* zantac (on Dr's advice)
* very cold milk
* steamed rice with thin soy sauce
* steamed potatoes and green beans with a little butter
* lemon sherbert lollies

but it really sometimes was a matter of going to the shops, walking around until I saw something I thought I might be able to keep down ...

but I hate to say, I had m/s for 32 weeks when pg with DS, and I still have m/s this time ...

there are medicines you can get to help, but personally, they make me too drowsy to function.
