Could you give a more detailed food log? Do you have a journal on MDA? I get migraines easily, but after having been following PB for a few weeks, migraines have disappeared. Also, are you drinking enough water and getting enough variety. If you are switching from a very processed and very high carb diet to Primal low-carb, you will continue to get headaches until your body has transitioned. Also, ensure that you're getting enough fat. Please provide more details since these are just assumptions based on what you wrote. Also if you could include age, weight, height and activity level, can help to determine if you're even eating enough.
