This site and this forum have been a huge help for me. Thanks all of you. I am a 54 year old male. I have been having episodic CH since my late teens. I am two weeks into what will likely be about five weeks of no fun. I am on a three year cycle. Thanks to you all I wrangled O2 out of my doc for the first time this time around and I am a believer!! She prescribed me a couple of cute little E tanks, an 8 LPM regulator and a cannula. This actually works for me but I was so jazzed I immediately went on ebay and got a bad-ass regulator, I bought an Optimask and I rented a 125 cu-ft welders O2 tank. Now I smack that beast good. I have a bubbler coming.

I am taking Topamax and so far I cannot say it is doing anything good or bad. I will be patient. My general routine these days is that I wake up several times during the night while dreaming with a K3-4. I grab the O2 immediately and can almost always knock it down in 10-20 mins.

My question is this - would wearing the cannula and running 1-2 LPM of O2 while sleeping act as a preventative? I am almost certain I have no sleep apnea. My wife reports that I do not snore and that I sleep just fine. I read about trying this on this board at one time but for the life of me I cannot find it now.
