eating to stop nausea?

I'm 7 weeks today yay! So exited already. I have sickness soon as I wake but then it stopps and I have nausea all day, does anyone find they constantly eat to feel better... I feel like I have to keep eating all day long snacking and meals 😂 I'm going to weigh so much 😂, I just can't stop! I have to have something at all times maybe a 15/20 min break, but it makes me feel better X
