I'v been using Oxygen for about 2 weeks now. I find that I need a flow rate of 15litres for 15 mins. This seems to delay the cluster for about 1 hour. I then use it for another 15mins but the cluster is back with a few minutes. Subsequent use slightly relieves the pain. My clusters usually last for about 5 hours and I get three a day. Any help or advice greatly appreciated.
