Same with me. Before i fell pregnant, i was such a hungry horse all the time! Then i kinda went off alot of food and as you say, the smell of some things made me ill!!
But i found out the hard way ITS NOT good to just not eat.. I wasnt feeling hungry, and was feeling ill one night and then all of a sudden i got the worst stomach pains i have ever had. God forgive me but i actually though i was loosing my baby

Later found out it was just bad hunger pains and was advised to just nibble on crackers or ginger biscuts if i was feel quezie, also drink plenty water ect just so i have something in my stomach..
