Lisa, I hope you are feeling much better and that the headaches are a thing of the past.
When I was much younger, I often got headaches. Like Chaim mentioned, diet makes a difference. At least it has for me. I gave up red meat in 1986, when I was 24. I eat very little cheese these days. I eat plenty of fish and salad ( with lemon juice on it and a little olive oil. ). It's made a huge positive difference.
