Thanks very much for the replies. I really appreciate this forum for the support and information from you all. Regarding a cure, I understand the part about the drug companies and profits - that there aren't enough numbers to make the research and development worthwhile. And I know that CH is considered "rare". But sometimes it's not the amount of people involved but the loudness of the voice that gets attention. I would like to attend the "Headache on the Hill" next year.I think weatherman is spot on when he says "someday, a really rich and famous doctor will encounter CH, dedicate his life to a cure, then this will all be ancient news". Until then we will keep battling the beast. It's been 14 years so far. O2 has been a blessing and we've dabbled in some other busting techniques and continue with narcotics for pain. Most of the other prescribed medicines were no help at all and may have actually caused more CH. It seemed like he was chronic when he was taking all the triptans. Since we quit those he is now episodic. Thanks again for your support.
