You can also try peppermint, lemon tea, ice water, or ginger. They also have herbal remedies you can try as well. When I was in my first trimester I worked at a food place and I had nausea really bad and what helped me was cutting a lemon and sniffing it out of a cup. Weird but it helped.! Good luck. Just a few more weeks and you should be feeling fine. First couple months are rough but well worth it. Good luck to you. And hope you feel better.
I think the Dr will prescribe you anti nausea medicine if you let them know how much trouble you're having.
