I had such severe all the time sickness, I had to be on medication (zofran mainly) and had to visit the hospital for fluids many times. However, some things did help the severity. WATERMELON!! That really helped. Peppermint tea with honey, and ginger root tea. Peppermints. Not the candy kind, but actual peppermint. I bought them in a health food store. I had to stop taking my prescribed prenatals and get something more gentle. If you have to take iron pills, that could cause it also.
