Hungry

16 weeks and a couple days here and I’m HUNGRY. All the time. Doesn’t matter what I eat, I still want more. I gained 70+ pounds with my first born and I do NOT want to gain that much this pregnancy. As is, they only want me to gain a total of 15 pounds this pregnancy but since I’ve been pregnant, I’ve gained 16. I feel so ashamed and grossed out by myself and my weight. All my pants still fit, but obviously are tighter around the belly, my sister says I look the same and so does my mum minus the belly again. But I’m in distress. How can I control this? I have no self restraint. I want to have self restraint but I goto the extremes with that kind of thing. The other day all I had was gum to chew until I got home and had dinner finally, but 10 hours of not eating caused my last couple hours at work to be very hard as I was getting faint and feeling out of breath.
