i keep stealing my coworkers snacks

so i have this weird habit where when im at work and everyone brings snacks for meetings or whatever, i end up taking them when no one is looking. its like this unexplainable urge that hits me all of a sudden, even though there are plenty in the snack drawer we all share. but why am i doing it? do i just want to feel something exciting? am i hungry or maybe bored and eating out of distraction? or is it because i think everyone will forget about one extra cookie or bag of chips and not notice its gone? its driving me nuts trying to figure it out, but also kinda fun in a guilty kind of way. im hoping this confession might help me stop.
