What to eat if I'm feeling nauseas after getting my wisdom teeth pulled?

I got all 4 of my wisdom teeth pulled 2 days ago. Literally the only thing i've eaten since the night before i got them pulled is 3 bites of smoothie, and 1/4 a piece of bread. This is because im feeling incredibly nauseas, anything remotely sweet like yogurt makes me want to throw up. the only things that i can imagine myself eating are salty things like crackers which obviously i am unable to chew right now. i think the nausea is because of the antibiotics because my oral surgeon said it causes that sometimes. but do you think it might be because i havent eaten anything? should i force food down my throat and if yes what food? thanks for your help
