what I do when I have pms is I try not to eat bad things . but just eat the good things like nuts , and other stuff. I feel like I am a bottomless pitt and never are full so I just eat all the good stuff and then know that in 3-4 days I will not be hungry all the time .Then during this time of year I would bring some treat with you to work so that instead of having everything that other people brought in you can have what you brought. good luck with not eating the bad stuff.
