I do not have the answer as to the why.....but I had the same problem with attacks coming back within 20 minutes or so of turning off the 02. Now I chug a Red Bull as I start the oxygen. Seems to prevent the comebacker. The kick to this is if you are caffiene sensitive, it'll make it tough to go back to sleep with    the night time hits.

You have had three excellent replies.  The only thing I can add is to look into Batch's ph recommendations.  I don't have them right to hand, and am not in a position to look for them at the moment either, but for some they seem to help with the come backs.

Dennis, Friedrich, I decided to not take Verapamil this cycle, as I was planning on taking the Clusterbuster route.
I have dosed 3 grams dried Cubensis ten days ago, and the same dose yesterday. I have had three hits yesterday since, but to my surprise I have slept all night long (it's 7:30 AM right now here in Northern Europe).
I hope that is a good sign, all I am feeling is mild shadowing. Keeping my fingers crossed!

Joe, I always have some cheap Red Bull/Monster knock off when in cycle, though I have to admit I am wary of using it in the middle of the night - I have no idea how sensitive I am caffeine wise and if I could sleep again.
Next time when needed, I will try your method though.
Thanks mate  .

Marc, unfortunately my regulator only goes up to 12 LPM, and yes I am aware it is too less to kill every hit.
When I joined here in my last cycle two years ago, I learned quickley that 25 LPM is the preferred method around here.
I have to say though, that this cycle the O2 has been much more beneficial than my previous cycle.
I guess I am slowly getting a grip on it. My 12 LPM will kill up to a 6 or sometimes even 7 on the Kip Scale, so I understand that higher flowrates must be much stronger in killing stronger attacks as well.
You think my neurologist would subscribe a higher flow if I requested it?

Jerry, I am sorry but I didn't get the Batch's PH reference. Could you direct me to it?
Thanks in advance.

Rebound headaches. "Rebound Headaches--A Review", Au. John S. Warner, M.D., in HEADACHE QUARTERLY, 10:3(1999). (There is some confusion on the board about the meaning of "rebound". There appears to be an emerging consensus in the medical literature to define "rebound" as a headache which is caused by the overuse of any medication used to abort a headache or relieve pain. "Recurrence" [of a headache] is being used to refer to the redevelopment of an attack when its "normal" duration is longer than the useful life of the medication which has been taken. That is, the medication effectiveness is reducing before the headache has come to an end; the pain redevelops.)

Sorry I dug up this old thread but It describes perfectly what I'm going through right now.

There seems to be some discrepancy regarding the use of redbull. With what we know now regarding the anti inflammatory regimen, are the energy drinks still recommended to help with reattacks while using oxygen? If the red bull is a calcium channel blocker will that effect the effectiveness of the vitamin D regimen?

Hey there cc45713 I would highly suggest buying one of the O2ptimask's. I have been using for a few  years now when my cycle hits and it really helps a lot. Also follow Batch's hyperventilation technique and advice on staying on O2 for a few minutes at lower flow rate after pain goes away.

Go to the Oxygen info yellow tab on the side and there is a link where you can buy the mask.

Hi feisty
the re-attacks that are described here are very similar to the pattern I experience. Attacks are spaced apart more during the day, but at night they come hourly. Thing is, it was exactly the same before I got the O2.

At 15 lts per min, a really deep breath will empty the bag, and it fills again while you exhale, so the bag doesn't really fill up faster than you can breathe. No doubt your husbands lungs have far greater capacity than mine (I'm a 64 year old female smoker)so he should be able to breathe more than 15lts easily.

Now, if I'm wrong here some one will come along and tell us, but I'm pretty sure you can't "overdose" on oxygen. The only symptom of overuse (that I know of) is hyperventilation - slight dissiness, prickly twitchy feeling in the skin - and hyperventilation is what we aim for. That is when the brain will reduce it's oxygen intake by constricting the blood vessel which is pressing on the nerve. But recurring attacks is the nature of the beast, and O2 will only abort, not prevent the next one.

Last night I went to sleep around 11pm. got hit at 12.30, 20 mins on O2 and back to sleep.Hit again at 1.30, same procedure, then 2.30, then again at 3.30. The only difference is that I did not get one at 6.30 this morning which has been the usual case for the past few nights. (Yaaaaay).    As batch has suggested I also take an imigran tablet - mine are 50mg - and that does help to break the pattern but I've stupidly let myself run low on them so having to ration them to daytimes only. I should be able to pick up some more today.

I do often have headaches which I am sure are just due to lack of sleep, but they are ordinary headaches - the kind that can be taken care of with over the counter headache remedies. My favourite kind !!!!

It will stop eventually and that is the time, when you are in less of a panic, to get well prepared for next time.
Maz.

Thanks feisty. Last night was the worst, but hey - I'm still here. What doesn't kill ya makes ya stronger - right?
