Oh I do feel for you both, you would think by now some more could be done for Migraines, my theory is they are either psychological, or dietary,
I think a lot of what we eat is the cause of a majority of problems, all the chemicals and preservative in food is frightening,
have you both tried decaf tea and coffee, I have it all the time, think nothing of it, I do it for heart reasons, also my parrot likes a drink and biscuit dunk in coffee and they have very small hearts and must not have caffeine!!
Good luck with the divorce Sue.
