Anyone else having this problem?

so I'm 12w6d and I get really hungry before I go to bed and when I wake up. Doesn't matter how much I eat, I still feel hungry and if I don't eat I get sick and I'm assuming that's because my blood sugar is low. but is there anyways to keep full? I've been drinking boost which keeps me going threw work and sometimes I'll drink it before bed. I just started feeling like this a week ago because before then I got out of my morning sickness at 9w and didn't feel like eating anything until 11w and then I could only eat what sounds good to me but nowadays my stomach is never satisfied with anything. I would eat a full bowl of cereal, 4 slices of toast and a cream cheese bagel that would last me 20 mins tops in the morning. i can't eat meat or eggs bc the baby doesn't like them and Everytime I force myself to eat them I get a upset stomach.
