Nausea :(

I'm totally having the opposite of morning sickness. I'm fine in the mornings when I wake up. Take my prenatals, drink water, tummy growling. And when I do eat something I eat like a bird so I don't get sick. Lately anything I eat my body rejects. I get the worse nausea by afternoon when I'm already at work, and I work until 10:30pm. Anything helpful I can eat to help my nausea. I know this is the brunt of the first few months of pregnancy but getting sick every day is just not my cup of tea :(
