Please don't take offense to Lances' question! We are deeply concerned with helping people alleviate pain...only to find out there was a far more sinister mechanism at work then CH. By our well meaning intentions of giving you methods to stop the pain, the "mechanism" causing your pain continues to grow until by the time it's diagnosed it's potentially fatal. A concern we wrestle with,,,including with each other!!!! On a regular basis.

Clearly you've done the footwork to get an accurate diagnosis so we don't have to sweat the scary stuff.
Oxygen. For me oxygen is only effective if I get on it at the first sign of a headache. If I wait until the headache is established, basically anything over a 5, it's not going to work for me and I have to go with a trex injection.

HOW you use 02 can bring out dramatic improvements in it's ability to abort attacks.
Since you're getting creamed at night, consider trying melatonin. An OTC sleep aid available at whole food or vitamin stores, I think even Wal Mart has it now. Start with 9 mg about 30 minutes before bed. Effective dosing varies greatly by person with some going as high as 18 mg. It affects your rem sleep and keeps many sufferers pain free thru the night. There was a thread awhile back that went into the differences between types of melatonin. It was generally agreed that the "good stuff" is:
n-Acetyl-5-Methoxytryptamine.
Some people take a combo of both the immediate release (to get to sleep right away) and the time-release (to stay asleep).
Have you ever tried verapamil as a preventative medication? Still the number one prevent based on track records around here. I stole this from Bob, worth printing out and taking to your doc:
A widely used protocol. Your doc will recognize the source and author:
Headache. 2004 Nov;44(10):1013-8. Individualizing treatment with verapamil for cluster headache patients.
Blau JN, Engel HO. Background.-Verapamil is currently the best available prophylactic drug for patients experiencing cluster headaches (CHs). Published papers usually state 240 to 480 mg taken in three divided doses give good results, ranging from 50% to 80%; others mention higher doses-720, even 1200 mg per day. In clinical practice we found we needed to adapt dosage to individual's time of attacks, in particular giving higher doses before going to bed to suppress severe nocturnal episodes. A few only required 120 mg daily. We therefore evolved a scheme for steady and progressive drug increase until satisfactory control had been achieved. Objective.-To find the minimum dose of verapamil required to prevent episodic and chronic cluster headaches by supervising each individual and adjusting the dosage accordingly. Methods.-Consecutive patients with episodic or chronic CH (satisfying International Headache Society (IHS) criteria) were started on verapamil 40 mg in the morning, 80 mg early afternoon, and 80 mg before going to bed. Patients kept a diary of all attacks, recording times of onset, duration, and severity. They were advised, verbally and in writing, to add 40 mg verapamil on alternate days, depending on their attack timing: with nocturnal episodes the first increase was the evening dose and next the afternoon one; when attacks occurred on or soon after waking, we advised setting an alarm clock 2 hours before the usual waking time and then taking the medication. Patients were followed-up at weekly intervals until attacks were controlled. They were also reviewed when a cluster period had ended, and advised to continue on the same dose for a further 2 weeks before starting systematic reduction. Chronic cluster patients were reviewed as often as necessary. Results.-Seventy consecutive patients, 52 with episodic CH during cluster periods and 18 with chronic CH, were all treated with verapamil as above. Complete relief from headaches was obtained in 49 (94%) of 52 with episodic, and 10 (55%) of 18 with chronic CH; the majority needed 200 to 480 mg, but 9 in the episodic, and 3 in the chronic group, needed 520 to 960 mg for control. Ten, 2 in the episodic and 8 in the chronic group, with incomplete relief, required additional therapy-lithium, sumatriptan, or sodium valproate. One patient withdrew because verapamil made her too tired, another developed Stevens-Johnson syndrome, and the drug was withdrawn. Conclusions.-Providing the dosage for each individual is adequate, preventing CH with verapamil is highly effective, taken three (occasionally with higher doses, four) times a day. In the majority (94%) with episodic CH steady dose increase under supervision, totally suppressed attacks. However in the chronic variety only 55% were completely relieved, 69% men, but only 20% women. In both groups, for those with partial attack suppression, additional prophylactic drugs or acute treatment was necessary. (Headache 2004;44:1013-1018).
=======================================
SLOW-RELEASE VERAPAMIL
Dr. Sheftell applauded the protocol for verapamil used by Dr. Goadsby and colleagues, which entailed use of short-acting verapamil in increments of 80 mg. “This method was suggested by Lee Kudrow, MD, 20 years ago as an alternative to slow-release verapamil,” Dr. Sheftell noted.
“I would agree with using short-acting verapamil, rather than the sustained-release formulation, in cluster headache,” he said. “I prefer the short-acting formulation with regard to ability to titrate more accurately and safely. My clinical experience anecdotally demonstrates improved responses when patients are switched from sustained-release verapamil to short-acting verapamil.”
Dr. Goadsby agreed that his clinical experience was similar. “There are no well-controlled, placebo-controlled, dose-ranging studies to direct treatment. This is one of those areas where clinicians who treat cluster headache have to combine what modicum of evidence is available with their own clinical experience,” Dr. Sheftell commented
I'll stop burying you with stuff to read. But please also consider the D-3 regimen I linked in my first response. 81% success rate is unheard of in CH treatment. As I mentioned, 3 years pain free myself after well over 30 years of episodic.
