Naseuous without throwing up.

Hi everyone,

As of today I am 10w1d and I've been naseuous since week 5-6 but have only thrown up once. Has anyone else experienced this? How many weeks did it last? Did anything help to remove the nausea? I am really hoping this doesn't last any longer. It's been sooo difficult to eat (as I am afraid of actually throwing up) and I've been very dehydrated (even though I drink more than 8 cups of water a day). Any and all advice is appreciated. :)
