Tegretol is given by weight. If you're a big guy, 600mg isn't too out there, but it's climbing. My new dose made my druggest gasp and insist on confirming with the neuro. What's sad is when we take big doses and get little relief.

You'll have to see how you handle the 600mg. I'd keep a journal to see if your headache increases along with the dose. A common alternative to tegretol is Lyrica. It didn't work for me and the withdrawl was murder, but some people really like it.

Have you tried accupuncture for your headaches? It's generally not that effective against PCS headache, but it's worth a try. I can't remember, has a good chiro checked out your neck for contributing issues? Some of the folks here also swear by biofeedback. I'm trying to save my pennies to give that a whirl.

Hang in There!
