Cleveland Clinic Headache Clinic???

I'm looking for someone who can tell me about the headache clinic at The Cleveland Clinic. It's been suggested I go there for two to three weeks. I'll happily go if their treatment can be of help, but I'd like to hear about it from a patient's perspective. The website doesn't give me enough information. Thanks so much!
