Superchick, we are the same person! I also work at my school all day.
Personally, I think the vending machine calls my name. Seriously. Especially, when it is about 2pm-3pmish...
This week, I've been shutting my door during that time and drinking water. Sometimes, or so I've been told, hunger is only your body craving water. Sometimes it has helped, but yesterday it did not. I ended up in front of the vending machine buying a pack of doritos and a 3 muskateers. I ate the doritos and 1/2 of the candy. And it was not worth it. I felt like crap afterwards. Today, I've brought a bag of popcorn, a granola bar, and a 1pt cake. Of course, I don't plan to eat all of those things. But, I've got my bases covered. If I want salty, I'm going for popcorn. Sweet-i'm going for the granola. And if I'm getting chocolate fix call, I might get the cake. (I'm PMSing...it might happen!)
Also, coworker's can be toxic! My coworkers love to eat lunch out because we have this awesome Pita-American cafe downstairs in our building. I have to BRING GOOD lunches to fight that off.
Best wishes, message me anytime
