Onward,

Imagine a white hot railroad spike driven into your brain behind your temple/eye for 45 minutes to 3 hours. Being a Chronic sufferer, I get no Seasonal or months-long breaks like most afflicted. I get hit about 5-8 times a week and I cannot use the most common, most effective treatment for curtailing Attacks - breathing pure Oxygen. I am incapable of breathing deeply enough for long enough for it to work.

Thank you for your words of concern.

Dave.
