Try some gateraide, for some reason when I'm feeling like that that's the only thing that will stay down.

The carnation chocolate high protein shakes (in the breakfast isle) saved me my first trimester. They tasted very yummy too!

water with lemon helps keep it down

Try a meal replacement drink

thanks @babygardner

Make she u are staying hydrated if u feel weak and dizzy go to the hospital so they can give u IV fluids. It was really rough for me in my first trimester hope u feel better
