Ouch

Had a little stinger last night, maybe k5 or so, and it woke me up about 3am. Oxygen killed it in less than 5 minutes. I love my regulator. The 40LPM setting really kicks ass at 3am. It's a bit noisy and usually disturbs my wife, but not nearly as much as me yelling, screaming, and smacking my head on the floor.

I was wondering if anyone had a demand valve rig. I have a few questions for them about the requirements. A demand system would probably same on the amount of O2 being used. Am I correct in assuming that if you aren't breathing in, it sends nothing? Unlike the traditional system that has gas flowing out whether you're breathing it or not.

I love my tank. It is green and gorgeous. It is cold, and warming at the same time. I think I am in love with my oxygen. Is that abnormal? I just wish I had a smaller rig I could take with me on excursions away from the domicile.
