What I find triggers an attack are:
1 Going outside on a cool morning (ie after having a shower) with wet hair, then later that morning I could easily have an attack
2 Early in the morning if a very bright light strikes my eye, (ie a bright flash of reflected sunlight off a window or passing car in a normally dim lit situation)
3 Often if I eat certain types of cheese, oddly enough, the next day I will have an attack.
If I take an aspirin as soon as I first notice any symptom of an oncoming attack, I find the attack is shorter and less severe, if it doesn't go away almost immediately. An attack often starts with a small blurring in the center of my vision, combined with a very slight feeling of nausea.

This is it! by: Steve W
What a relief. This is exactly what I see about halfway through. The episode lasts about 30-40 minutes, starting with a little disturbance feeling then a spot in the center of my vision. The spot expands into a crescent of kaleidoscopic distortion on one side or the other, then gradually clears out the side. I have no other symptoms at the time unless the aura itself makes me anxious. The best self diagnosis I have found is "migraine aura without headache" - see http://www.relieve-migraine-headache.com/silent-migraine.html. I get one every 3-6 months but have gone 2-3 years without one. Rarely I have had 2 or 3 episodes in one month.

Looks familiar! by: James
Sure enough, that looks like how a lot of people describe and draw their visual migraine aura. Well done.
