I really didn't/don't have morning sickness (26wks), but the smell of certain things make me sick/hungry.
For instance, popcorn, my favorite snack, is now making my sick when someone cooks it, along with eggs. If someone is cooking eggs, I have to be out of the room and spraying febreeze!
on the opposite, I made a deer meat roast (smells like ground beef btw) and when I put it in the crock pot, I almost licked my fingers it smelled so good raw! Sry to gross you out if I did

I know Veggies can't stand the talk of blood...
