This is a message for Richard, who was in the chat on Wed.
night. Richard, you can get a small tank of Industrial Grade
Oxygen for about $20 at a welding supply store. You might want
to invest in a regulator as well for another $10. Refills
are cheap. You take in the empty and they trade you for a
full one, probably about $7. It's not as pure as the
medical grade, but it's better than no oxygen. I do
metalsmithing and so I tried sniffing my O2 tank when I got
a headache, it did not help me significantly but it did
seem to help somewhat. Hope this suggestion helps you.
