Morning sickness CONSTANTLY need help

I have about 8-10 vomiting episodes a day for the past week. Tonight has been rough I ate bland food all day just plain toast, grapes and drank plenty of water. It seemed it didn't help and I was still hungry but nauseated. Hubby was feeling pizza tonight so I agreed I'd try he was tired of bland food also. I have been up all night already throwing up that pizza. Any Advice on things that have helped. Anyone else with this problem
