I suffered from constant migraines and tried everything too. I tried the DHE as an inpatient for 5 days. It helped and bought headaches down to a 2-3. This was a huge break for me. It last only for a couple of weeks but I welcomed the break.
about a month later I was admitted for an 8 day treatment for the DHE. I left with out a headache. 2 days later I had appendicitis ( nothing having to do with the other just bad luck!). I was headache free for almost 2 months. I would do it again in a second.
I also have have had Botox. My migraines have started coming back again, everyday. If I can not find a way to control them I would try the 8 day hospitalization stay. It was well worth it.
Best of luck
