i had no dx of migraines but i am sure i have had two - one in the early 80s and one in the mid to late 90s. the 80s one came on in typing class - yes, typewriters hehe - and the 90s one at a temp placement in an office.
the big change in my life for that 90s one, was that i was drinking and eating caffeine (black coffee and it was a placement at cadbury's) for the first time in years.
do caffeine and chocolate make sense as the triggers? i don't know. possibly only the *change* from no choc and coffee to some (which means up to 2 cups coffee per day and probably more sugar - you know 'fuzzy peach' 'orchard pear' and all those things - than actual chocolate in terms of snacking). by comparison i think i have a lower chocolate intake now and possibly higher tea and coffee intake. no migraines or even headaches. it was weird though, i was okay in a daylit office with the lights out, instant migraine under the fluorescents. i could literally step in and out of a doorway and go instantly from no migraine to a migraine complete with lightning creeping across my field of vision.
i hear high copper can be a culprit for migraines.. i was largely in vegan mode back then, could have been copper overload.. but then why did i only get that one migraine, and not many?
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
