I have the same problem with my husband. He'll bring home snacks and he can eat portions like that, while I tend to overeat or at least eat daily till they're gone.
Just right now I stress ate a whole meal when I just had breakfast less than two hours ago. I'm nervous because I have to go out in the snow. Drive or walk? Driving makes me nervous even without snow and with someone, but I'd be alone in this snow...but I don't know if I can walk and handle the cold either.
