I cooked gallons of chicken soup and we almost had to buy a saltine factory for my wife in her first 4 almost 5 months of pregnancy.
She would be so hungry, eat, throw up, and come back and eat and then start all over again.
It would probably be a good idea to ask your hubby or mom or someone to cook up a bunch of lightly seasoned chicken or turkey or even vegetable soup and get lots of saltine crackers and ginger ale.
It was a miserable time for my wife but once she was done being sick, it was like a miracle. She just didnt get sick again. It was finally over.
Also, do like joanna said, eat light meals many times a day. The baby will get all the food it needs by default but you can become very malnurished because you cannot keep food down for the 2 of you.
Another think nicole did was eat peanut butter toast in the morning. That would stay down and nestle chocolate milk. They are not cheap but I could have her breakfast done and her lunch packed in 10 minutes before she had to be out the door.
Good luck,
