Natural Remedies for Migraines

I have had migraines for my whole life including my mom, sister... Each time the weather changes, rain snow thunder comes cold to hot, hot to cold really horrible migraines happen. I have tried all the remedies, supplements, diets I could find and now the only thing that completely works is unfortunately a prescription drug called sumatriptan, I wish I could understand why and how I can find the equivalent effects in a natural remedy, so I never have to take it again....any idea??
