I've suffered with nausea for years now. I was prescribed Zofran while in the ER and have to say it is a wonder drug. It also comes with a wonder price. It is EXTREMELY expensive.
Good luck to you, I know how you feel.
Yeah, you should try ginger. I don't really like the taste of it myself, but it is often recommended as a natural remedy for morning sickness and general nasea. But I don't know how serious your problem is. Well, it might work.
