While caffeine is a trigger for me, and I normally avoid it completely, I find that once I get an aura, I can usually prevent the full-blown migraine by taking several ibuprofens and a cup of caffeinated coffee.

The auras were scary before I understood what they were, but I'm glad that I get them because the warning saves me from a major migraine.

Fortunately, I rarely get them any more since I went caffeine-free and got past menopause.
