Welcome to the board Davey, the good news is there is a LOT of good stuff available now to keep ya from hurting.. .. I’ve had CH for 35 years, they haven’t killed me yet! You need an organized approach to managing them so they don’t manage your life. I use a 3 pronged approach, many use a similar approach:
1: A good prevent med. A med I take daily, while on cycle, to reduce the number and intensity of my attacks. I use lithium, it blocks 60-70% of my attack. Verapamil is the most common first line prevent, topomax also has a loyal following. Some have to combine lithium and verapamil together to get relief.
2: A transitional med. Most prevents will take up to 2 weeks to become effective. I go on a prednisone taper, from 80 mg to zero over a two week period to give me a break while my prevent builds up. Prednisone will provide up to 100% relief for many CH’ers but is harsh on the system and should only be used for short periods of time.
3: An abortive therapy, the attack starts, now what? Oxygen should be your first line abortive. Breathing pure 02 will abort an attack for me in less then 10 minutes, that’s completely pain free. Read this link as it must be used correctly or it will not work

Imitrex nasal spray and injectables are very effective abortives. I use the injectables, they’re expensive, and I rarely use them, mostly just when I get caught away from the oxygen. The pill form generally works too slow to be effective for CH’ers.
You mention most of your attacks are the nocturnal variety. Many have found they can reduce or even eliminate the wake up call attacks with Melatonin. It's an over the counter sleep aid available at health food, vitamin or drug stores. Start with 9 mg about 30 minutes before bedtime. May have to adjust the dose up or down, up if it's not helping, down if you're a zombie in the morning. You might have to play with it a bit, some get the best results by splitting the dose in half between slow release and standard release. Standard release to get to sleep, slow release to get ya thru the night.

It’s a vitamin/mineral/fish oil supplement, all over the counter stuff, that’s providing a lot of relief for people who have tried it, it’s healthy for you even without CH!
For now, get some energy drinks. Rock Star, Monster, any containing the combo of caffeine and taurine, chug it down as fast as you can when you feel an attack starting. Many can abort or at least really reduce an attack using these.
Finally, visit our sister board for “alternative” treatment methods outside of mainstream medicine. As you’ll see from all the success stories on this board, there is something to it.
