Has anyone undergone the Raskin Protocol (a 3 day treatment of DHE45 in the hospital for migraine?

I have had 2-3 migraines per month and daily headaches for the last 3 years. Before that I had the same problems, just not as often--it keeps getting progressively worse. I just saw a new neurologist (the fifth one in 3 years) and later this month I will have this treatment. He says I have transformed migraine and that the daily headaches in between migraines are also migraines, just less severe. He says this treatment should stop that constant pattern and after I will only have episodic migraines, maybe 2-3 a year. That sure would be nice! I was wondering if anyone has tried this?

Thanks, Penny
