Visual migraines (migraines with aura) triggers

[David_H]

Hi all, I have had these migraines on and off for a few years now. Symptoms are, no headache, visual disturbance usually starts in the very central vision which then turns into a zig zag pattern which gradually disappears across to the periphery of view before disappearing entirely. The episodes average around 20 mins. I have experienced it after drinking red wine and have a recollection of eating some stilton on another occasion. I'm used to getting them every 2 months or so but unusually experienced it the last two days in a row. The only thing I can think of on this occasion is having eaten some chocolate (more than I'd normally have on these occasions) an hour or two earlier.

Have others had similar experiences and have they identified their own triggers (food, stress, sleep issues, etc)?

Thanks a lot Dave
