does some food bother you?

so I could eat onions on my cheeseburgers and eat onion rings. but I'm now 7 weeks and the smell of onions makes me want to puke and if I get a cheeseburger with just a little itty bitty peice of onion that's all I can taste! does anybody else have this problem? if so tell me what food you can't stand but use to be able to eat!
