Your doctor will probably recommend this anyway, but the first time you inject this drug make sure you are under medical supervision. I took it having no known drug allergies and with no reason to think I would have a bad reaction and I thought I was going to die. The pain in my head got worse and worse (yes, suicide-inspiring is a good phrase) and I kept vomiting long after there was nothing left in my stomach. I got so cold that even with heaps of blankets and heating pads I was still shaking and finally the doctor just sedated me to put me out of my misery.

I know this drug must help some people, but I would seriously look at alternatives before you jump into anything. I've almost entirely eliminated my migraines by cutting out caffeine, alcohol and chocolate from my diet and by getting enough exercise and sleep. It's a lot safer.
