S.S.
My midwife told me to take vit. B6 and half a unisom in the morning. Worked like a charm. Dr's use unisom for Hyperemesis gravidarum (medical term for excessive vomiting of pregnant women). You can find info on unisom on wikipeda. The standard treatment in most of the world is Benedictin (also sold under the trademark name Diclectin), a combination of doxylamine succinate and vitamin B6. http://en.wikipedia.org/wiki/Hyperemesis_gravidarum
