There's some good evidence behind ginger and it is a great natural choice for some people (sorry it didn't work well for you!)

For me morning sickness was a lot like a hangover - I could make it better by eating, the greasier the food was, the better. Which is why I put on a lot of weight in each of my first trimesters. However, it also relates to effective advice - eat small portions of protein all the time. Unlike a "stomach flu" - most people feel worse if they don't eat when they have morning sickness.
