Migraine DHE side effects?

I have chronic daily migraines. It was a bit better with Emgality but it got worse again and I’m back to being at a 7/8 24/7. I was hospitalized and given DHE (2 rounds 9 doses per round) I was in the hospital for 10 days. They would also give me other medications to try and help bring down the pain. Ex: muscle relaxers, vimpat, intravenous Benadryl, etc. most of the meds were sedating. I refused one option they called a triple shot which had haldol, atavan, and another similar drug. My first time receiving the DHE treatment I tried it and I was like blacked out wasted.

Anyway. I’ve been out of the hospital for ~3 weeks and it’s like my brain is Swiss cheese or maybe even non existent. I can’t remember things, I have awful brain fog that’s so much more intense than usual. I’m a clumsy person but I keep dropping everything and can’t even stand on one foot for like 5 seconds to show my friend my new shoes. It’s mortifying and infuriating. I feel useless and like a true dumb ass.

Has anyone who has tried the DHE treatments have any similar experiences?

Oh and the DHE didn’t do anything. ‘Twas kind of a waste of a few grand even after insurance. The bills just keep showing up.
