GINGERRR!! It's a herbal remedy for nausea and it really works. Everywhere I went, I carried with me a big bottle of ginger ale, all through the 1st half of my pregnancy. Chewing chystalized ginger is meant to be even better. Even if you don't like ginger, I promise it will help!
There's also stuff you can get from the pharmacy, herbal things . . . that contain ginger
