Hypermesis Gravidarum - Help!

I am 8 weeks today. Two weeks ago I was diagnosed with Hypermesis Gravidarum.

For those who don't know what that is....it's severe morning sickness during pregnancy.

I've been in the hospital twice already because of how dehydrated it has made me.

I cant keep anything down. Food. Liquids. Nothing. I was prescribed Zofran and it was working for a little while, sort of. Now it doesn't help at all.

I am to the point where idk how much more I can take of this. I feel horrible all day every day. I am unable to go to work. I can barely get out of bed without having to rush the the bathroom.

Has anyone else dealt with this?? What foods helped??
