I think mine are mostly b/c I don't eat enough. I have started induction several times over teh past few months, and the headaches get so bad I start eating sugary snacks to make it go away. And this is after a week or more! I amy be more addicted to carbs than I think, but I believe after reading this board, I need to eat more frequently, Lo carb and hi protein. I start tomorrow. Wish me luck!
