There are the foods you should be eating... You know, iron-fortified foods, brown rice, lentils, dairy products, fish... all supposed to help with PMS and all, frankly, bullshit. We don't want them, we don't eat them. We find our own ways to get through the inconvenience of bleeding from our vaginas.
My Top Ten Period Comfort Foods:
Leftover tortilla chips all crunched together with salsa in a bowl, eaten like it's cereal. (That way you know an appropriate portion size.)
Nutella on anything, especially something salty.
Smoked mussels or oysters.
Cream Cheese icing - out of the can.
Dill pickle chips.
Chocolate Raspberry Martinis - from my emergency freezer flask.
Cheez-Whiz on toast. Or, if it's really bad, Easy Cheese sprayed from a can directly into your mouth.
Chocolate covered pretzels.
Ridiculously priced Ben & Jerry's or Hagen Daas from the tub.
Home made Turtles*: Chocolate chips, pecan pieces drizzled with caramel sauce into a bowl - eaten with a spoon. Repeat as necessary.
*If you have the patience to make and then wait for the actual candies try this recipe.
