Psychedelics for Insomnia?

Hey fellow Psychonauts,

I have severe chronic insomnia (can go days/indefinitely without sleeping, resistant to medication.) I’m seeking any anecdotal stories or links to literature of anyone who has taken high dose psilocybin or DMT (or) for treating/curing insomnia, from a neurogenesis/creating new neural pathways/severe anxiety relief perspective. Is this possible, or just fanciful thinking?

Cheers!
