I had hyperemesis and nothing helped me. Sometimes a fresca would settle my stomach, but other than that I had to rely on zofran.
You could try taking extra vitamin B. That helps a lot I guess!
I felt the same way when I was pregnant with my son... I almost wished I would throw up so I would feel better. It helped me to eat frequently, small meals. If I got hungry it got worse than I felt too sick to eat. Also, staying hydrated and laying down for a nap too. Only a few more weeks and you should start to feel some improvement heading into your 2nd trimester. Hang in there!
Lemon oil or peppermint oil in a rag or in tea. Or just some crackers. Ginger ale is good also.
