Marina Brasil I'm so sorry about your migraines. I feel your pain. I used to get a migraine every week that would put me out for 2 whole days. I became depressed as well because I couldn't live that way, I felt that I couldn't do anything ever, I spent all my time either having a migraine, or recovering from one. It sucks. I was on a preventative pill for a while (forgot the name) and Relpax (helped a lot if I took it when I felt the migraine coming on). Honestly, what helped me the most was finding ways to remove stress from my life (not an easy thing to do, that's for sure). Now I only get one very rarely (under lots of stress). Mine start at the bottom of my neck, so I always have an ice pack in the freezer to use, and these "migraine cools" I buy at CVS (cold patches) that I keep in my purse at all times. If I'm out and about and I feel it, I'll stick one on the back of my neck and keep going, it helps relax my muscles and usually stops it from starting. Unfortunately if I miss that window when the stress is coming on, there's no way to stop it, I just have to knock myself out somehow in a dark room until it goes away. I've also found that making sure that I'm hydrated helps, as well as knowing my triggers (foods, stress, neck pain, etc). Red wine is a HUGE trigger for me, I avoid it like the plague now. For some reason white wine is fine, red is killer, I'll have a migraine by the end of the night. So I guess my advice isn't all that super, but everyone's migraine triggers are different.
So basically, know your triggers, and take little steps to help prevent the migraines from ever happening. When they do, unfortunately coping mode starts. But if you kind find a system for calming yourself, whether it's deep breathing, doing some stretches (works for me, I do neck stretches in the shower and let the hot water run over my neck and shoulders, then ice on it when I get out, helps me a LOT) or lighting a calming scented candle, you can teach your body how to calm back down. Or, maybe you need to talk to your doctor about a different medicine, and other advice regarding prevention.
Good luck! i hope you find a way to make the awful migraines go away.
