Hey Steve,
Welcome aboard and sorry the beast has returned.
We're all wired differently, and different medications have varying levels of effectiveness on each of us with no two exactly the same. Having said that, the odds on favorite and most effective regimen of intervention for most CH'ers involves a three-pronged strategy laid out by Dr. Todd Rozen, MD, FAAN, while he was practicing neurology at Michigan Headache & Neurological Institute in Ann Arbor, MI.

This three-pronged strategy involves:
(1) A prednisone taper as a transitional therapy for a week to 10 days. Under ideal conditions, the prednisone taper will abort the bout, but usually, it provides the time and pain prevention needed while titrating the dosage up on a preventative.
(2) A preventative regimen, usually verapamil, that's taken by titrating the dosage a little higher each day up to a preset limit until the prednisone taper is complete
(3) An abortive strategy with prescriptions for oxygen therapy with a non-rebreathing mask and flow rate of 15 liters/minute and triptans like sumatriptan injections or nasal spray to catch any burn through CH attacks. (Oxygen therapy at 25 liters/minute and much higher is even more effective with shorter abort times than 15 liters/minute).
After the prednisone taper is complete and the verapamil has had an opportunity to prevent all on it's own, the variations start if there's been no response to the verapamil dosage or the burn through CH attacks are still too frequent.
The National Guideline Clearing House lists the following standards of care for treating cluster headache with the same methods of intervention listed above:

This came from the European Federation of Neurological Societies (EFNS). Several of us have met with many of the neurologists that developed this standard of care as well as Dr. Rozen, so there's good agreement among the top neurologists here in the US and in Europe on the most effective methods of intervention for cluster headache.
All of these neurologists see CH'ers on a daily/routine basis so have more experience treating our disorder than most.
The cluster headache survey many of us took in 2008 lists these same medications as the most effective. There were 1134 complete surveys so that adds up to a 95% confidence level in these results.
If you think your doc will agree to write you a script for oxygen therapy, you may want to download and print the following link on "How to Obtain a Properly Written Rx for Oxygen Therapy" and take it along when you ask for the Rx:
