My chronic migraines with related sinus inflamation were triggered by the slightest change in weather conditions. The migraine frequency had escalated to the point that it was rare for me to have a truly pain-free day. I was initially disappointed with this product as it seemed not to help, but after faithfully taking it for several months, my headaches gradually reduced in frequency and severity to the extent that now I think I may actually be completely free of them!!! If you have headaches - give this a try!
