Dear Lady D,
I think you replied to the wrong person here, I find caffiene helps gaurd against headaches, but that is my personal opinion, ha!ha!
Stress can be a big factor in migraines too, i do not get them much but when I haven't slept well and under heavy stress I get migraines at least 2 times a year, but since I have been on anti-convulsants for bipolar, I haven't had any migraines, in fact last year on the news they showed on a medical clip that anti-convulsants were very successful for migraine sufferers.
Always something new coming out, and some things actually work, ha!ha!
much admiration to you Lady D for being able to rid your system of caffiene, I am addicted to the stuff and if that is my only vice that is fine by me, ha!ha!
Take care
"darkeyes"

Without my coffee my darkeyes would have dark rings too, ha!ha!
