Dear M.,
I feel your pain. I've been there as well, in all my three pregnancies. One home remedy that you can try, which it worked for me in settling my stomach down is this: a cup of grits, thinned with water. it has no flavor, no strong smell that will evoke nausea. Just follow the box cooking directions and add more water to drink it in a cup.
Also, if you are not allergic to corn flower, this will also help settle your stomach. This is called "Atole Blanco" it is made from corn flower used to make tortillas. get a half a cup of corn flower and dissolve it in two cups of cold water then add to two more cups of boiling water, stir constantly until it begins boiling again and then simmer for 10 minutes. let it cool and drink in a cup. This helped me take in fluids. I was not capable of keeping even a glass of water down, but with this, I was able to drink this fluid without throwing it back up. I hope this drink will also work for you.
