Years ago (and crossing everything at the moment) I had those long term...for days bad headaches...migraines. Wow. Hideous!
Usually, I ended up at the ER and got some kind of shot to stop the cycle.

For me, I had to get on a low dose of Topamax and do many, many other...I guess you might say more holistic things...to get some improvement.

I use vitamins (calicum/mag., B Complex, Co-Q10) in particular, relaxation techniques and carefully avoid triggering foods.

Additionally, I am careful when it comes to stress....doing my best to think positive, controlling what I can in life, exercising, etc.

They are still an issue...but improvement has come. I think everyone is different....for me it was a big process....Topamax (low dosage...anything more makes me loopy), lots of hard work and serious thought... with the help of a really caring, wise and patient doc.
