Constantly hungry

LJ • Baby girl born Feb 19, 2015 and second girl born Jan 20, 2017. Baby #3 due in October!
I'm just over 8 weeks along and constantly hungry. I'm trying to eat small meals throughout the day but I don't ever seem to be satisfied. So far no cravings and a few aversions. I get nausea but not to the point of throwing up. I'm also trying to drink more water but most times it makes the nausea worse. Does anyone have suggestions to help me out?
