South Beach diet good for headaches?

I get chronic headaches: frequent migraines (several each month) and almost daily headaches. I drink plenty of water for the most part, don't smoke any longer, don't use drugs, and rarely drink. And still I get headaches. The migraines are genetic in my case - all the women in my family get them.

Since I've been on the South Beach diet I have not had one headache. I'm incredibly happy with this. I have adapted to my headaches; I've suffered from them for years, so I've just grown accustomed to having them. Now that I'm not having them daily, I'm amazed at how differently I feel. Combined with a very healthy diet and even more water than before (which means far less coffee and no soda at all) and regular exercise, I feel physically terrific. My mood, general outlook, and depression have all improved greatly.

We're also spending less money and generating less garbage; we throw away almost no food now, because we're eating it all. And, in another five or ten pounds, I have fourteen pairs of pants and ten skirts and dresses that I'll be able to wear without greasing down my thighs first.
