Phenergan,
zofran, ginger, something with not a whole lot of flavor, ******* pops, sipping on ice cold water, sucking on ice, etc.. I had severe vomiting while pregnant(there's a medical term for it) and had to do all of that for the first 5 months! They even gave me the Phenergan and told me to put it up my butt bc it would help better... embarrassing!
