Is a prescription the only way to get O2? My husband gets CHs, though he went without them for over a year so we thought maybe they were gone. But the last 4 nights he's gotten one, and the one he had today was one of the worst he's ever had. *sigh* And on vacation, too--figures, eh? Anyway, we wanted to get some O2 since he's apparently in a cluster now and the usual imitrex and zomig don't seem to be cutting it this time around, but since we're out of town we don't have a doctor here to go see. Are we out of luck or is there a way we can get some?

Visiting ER can help perhaps. Also there's fire stations. Their set-ups may not be exactly as prescribed at ch.com but any port in a storm.
