Interesting you mention oxygen -- this means you breath from an oxygen tank? I notice I yawn a lot when a migraine is about to occur -- I always thought this had something do with lack of oxygen. I always have a supply of MaxAlt (rizatriptan benzoate) with me which short circuits my migraines if I take it in the correct window of time. 1 MaxAlt usually works, 2 or 3 in the worse case.
