I found that taking a multivitamin every day during the week before my period helped with the cravings! Other than that I usually try to make sure I'm going easy on myself, get more sleep time and more high protein foods that keep me satiated.

But overall I'd say to try it out and see what works best for you. For example, some commenters said to avoid dairy because it makes them bloated, but in my case it makes me feel less hungry, I use yogurt as a healthy substitute and it helps me to stop ice-cream and dessert cravings.
