...ummm....yeah ^^^^^^^^
.....out of hundreds of cycles when ECH, there were a handful of the "one hour wakies" type for me (handled differently, see prev "wake up"posts). no changes in nothing before or after. while there are always tweaks you can make to O2 usage, i know i never varied far enough to prevent oxygen from being its typical sanity/life saver. something else happened (physiological?) ....and just like ALL our other tools "sometimes", for some, it just stops working/works differently....hopefully only for a while.
....O2 never has been, don't see how it would ever be, anything but a most effective abortive (don't forget the caffeine/taurine). it is transitory, not a prevent, not a trigger.....
....as an ultimate believer in O2 i must add: before any clusterhead gives up on O2, they would be WELL served to insure: a non rebreather mask, lpm 12-15+, and a practiced breathing technique(slow breathe, breathe/hold, hyperventilation, combo).....
