i have been taking 10mg of Flunarizine for a long while, only one pild when the migrane can not be manage with other drugs like ibuprofen, aspirin or even ergotamine, and that's it. It work perfect with one pild at night if the migrane become chronic, after the migraine without the pild, the life is totally normal for me and i have been without severe migraine for more than a year, but if the pain is so extreme, and can not be manage with any other soft drug, i definitely recommend it
