24 weeks

So woke up the first time out of this pregnancy....SUPER hungry!! Like beyond hungry!! I ate and hungry again!! Woke up at 3am to eat, all the way through 11am....hungry I've had grapes and apples and soup and cereal like it's a uncontrollable hunger anything I do I cannot get full and feel like I'm starving....normal? I started at 221lbs and my doc said she doesnt want me gaining more than 25lbs or less in this pregnancy but then this uncontrollable hunger hit..
