Sometimes actually "tossing your cookies" can help your stomach to calm down. I've always had severe nausea with all of my pregnancies and I discovered that instead of waiting until I ate everything ('cause I needed something in the stomach before my body would do anything) and couldn't keep it down after eating, that I would eat a little and actually let my body go through with the vomiting (even though I hated to), and then could finish the rest of my meal without throwing it all back up and actually feeling somewhat okay with something in it.
I never found anything to be helpful aside from the above. I'm sure I tried everything in the book. Some things even made me sicker. Fortunately it only lasted the first tri-mester.
Good luck and congrats!
