I have also tried turning regulator off between breaths, usually when my tank is nearly empty.
My best tip is to set an alarm to go off every few minutes. When my headache goes I often fall asleep and the alarm reminds me to turn off the cylinder.
Luckily, in UK prescriptions are cheap(?)and the real fear is running out, not cost.
