FYI, my doc at Diamond Headache Clinic in Chicago just told me about ENFORCE. A 3 year drug trial underway for CH. Asked me if I am interested when my next cycle arrives. Have to call very early in cycle to participate. Probably have to not use certain other meds though Verap was OK.

Googled ENFORCE and found Wakeresearch.com who appear to be running it. That's all I know other than my Doc said it sounds promising. Just wanted to give a heads up in case it's worth pursuing for anyone.
