What a frustrating experience. I know inpatient clinics aren't effective for some people, which is why I've never bothered. Particularly with Famous Headache Clinic that most people rave about. Sometiems I wonder if they are mostly effective for people who feel like they've tried everything, but have really only scratched the surface. I know that doesn't apply to everyone, including Vicki, but it's a thought I've had.
Your headaches certainly aren't your fault! I know it can feel like they are, but no one is truly at fault for this. Some people are just so special that they elude typical treatments.

Hang in there. You'll get through this -- we all will. (How's that for platitudes? But I really mean it!) There's a great quote from Winston Churchill: "When you're going through hell, keep going."
Take care,
Kerrie
