2nd pregnancy hunger

2nd pregnancy and I'm currently 8 weeks. This pregnancy is very different from my first. My vomiting just stopped, but feel nauseous every night. Also, I can sleep through the night without feeling severe hunger. I put my toddler to bed by 9pm to latest 10pm. And I knock out as soon as my toddler sleeps. I do have insomnia at nights. Is it normal to not feel hungry or wake up to hunger pangs at night?
