Hunger/ morning sickness

Sarah • I have two beautiful children a boy and a girl. TTC baby #3
Hi all. So I'm 8 weeks along and I work at a daycare. I work from 830 am to about 5 or 530 pm. My issue is about 3-4 I start getting hungry and by the time I'm off at 5 I'm feeling like I'm starving. I eat a fiber bar around 345 pm but someday it doesn't feel like I ate it. How do I stop feeling starving (and eat so much once I get home). Because the feeling sucks.
