Also as mentioned before, the shots seem to work better in most people thatn the pills. Maybe because they get into your system faster.
I also have 'he**graines', and have treid everything under the sunm and the inimtex injection works wonders. That plus Phenegran for the vomitting. But sometimes it gets so bad I have to go to the ER...the bill sucks but it's worth it to not be in agony.
good luck
