Yeah...very strange. But I feel for you. Right at this moment I'm trying to have one. But it's not materializing. Earlier today my vision dropped out for a second but then started back up without any further issues.
So the other night I had Khalua and coffee and downed two freshly shredded beets with balsamic vinegar while I was having my aura (I did this as an experiment in lieu of Imitrex). Fortunately I don't get sick during a migraine, on the contrary I could eat anything sweet - the sweeter the better - so I thought I'd take a chance.
As I understand it, triptans sort mimic the effect of alcohol and caffeine on your arteries when taken in combination. So alcohol tries to relax them and caffeine tries to contract them - so the two of them fight and the activity of the artery is evened out. Beets are very high in natural nitrates which reduce blood pressure. Believe it or not, maybe it was a fluke, but I did not get the headache or the pain spot like usual. My aura passed and I had no further occurrence of issues. However, the day after I was very light sensitive and sound sensitive.
I'm actually leaning towards either a chronic Lyme infection or pseudo-tumor (idiopathic intracranial hypertension or ICC) as the real source of my migraines. I also have tinnitus and it gets very swooshy during a migraine (something I read about ICC and tinnitus connected some dots). The problem is that you need a lumbar puncture to check for high pressure in your spine and then you go on diuretics. The Lyme issue, if indeed that's the problem, would be a year of powerful, thyroid damaging fluoride based antibiotics.
