Hey all,
  My name is Paul and I've had clusters for 10 years now, and just killed one off about an hour ago, no O2. I just started another cluster-bout about 2 weeks ago, and I'm getting 1-4 a day. My bouts usually last a couple months, then leave me alone for 6-12 months.
Just this week I finally gave O2 a shot, and it worked like a charm. I only have a 6 LPM valve, but I hyperventilate like crazy, and take around 6 blasts of air per breath, or in & out quickly. Its my aunts tank, and its the kind that gives a shot of air out while you inhale. I just inhale a lil bit, stop and start again so I can get it to shoot again. After 6 shots I inhale, and start over again.

I've read up on the valves and masks to buy, and I'm getting a setup soon, yet this works for now. I'm so happy that I finally found something that works, yet I know its not childs-play so I wont use the O2 without someone watching me for now. I know CO2 can build up, so until I get a real setup I use caution.

I'm also so happy I found this place, and that theres places like this where we can support each other, and learn about therapies, medicine and everything related. I've never tried anything that worked one iota on my pain, until O2. My 9/10's are reduced to 2/10's if not gone completely in 5-15 mins. Although I've only used it 3 times now.

I live near Calgary, Alberta Canada, and I'm wondering what type of Doctor/specialist I should see regarding clusters? My Dr didn't seem to know what they were when I mentioned it, but I'm hoping she's done some research, cause I'm going to see her soon. Yet I'd like to see someone who knows lots on the subject, like maybe a neurologist?

Maybe I'll ask that in a place it belongs, later.

I've read its believed that dilated blood-vessels in our brain that put pressure on the Hypothalamus, is where the Beast comes from. Thats encouraging to hear, and sounds plausible to me.

To those who moderate, administrate, and have created this site, Thank you. I've found other places in the past that were informative and helpful, but this site has it all, in a well organized, easy-to-use manor.

Please, keep up the good work.

Thanks Joe. Very helpful. I also have a heart rhythm problem called Arrhythmia or specifically SVT - SupraVentricular Tachycardia, so energy drinks and strong coffee can send me to the ER. Although I do drink coffee and find it helps, I just cant over do it.
