HI there,
I totally understand where you are coming from and yes..the computer can cause migraines!!
I sit at one all day also and I have learned that I have to get up and get away from it or my eyes start twitching and then the migraine hits. Have you ever tried Elavil ?? It is a preventative med for depression and for migraines. I have been taking in for years and it does work.
Also it could be what you are eating...get rid of cheddar cheese,,,parmesan cheese,,any aged cheese products..lunchmeats..anything with msg in it...
chinese food,,,mexican food,,, I had a neurologist do the food test and it worked ....
keep us posted and good luck..keep a journal what you eat and when you have the migraine..etc.
