Curcumin (after a few weeks) eliminated my headaches completely, and they were terrible at first. I couldn't even move at times, and I had to have all the lights off.

I still have constant pressure in my head, but the headaches are gone. I guess the pressure could maybe be considered a headache, so I've noticed that rest, frequent breaks, and a full night of sleep help the pressure go away. I also can't handle much sugar. If I eat a piece of chocolate or something, my head feels like it is going to explode. On the days that I manage to avoid sugar, wheat, and dairy, I feel very good.
