In this interview, Jordan Peterson discusses his journey around the world trying to find relief from benzodiazepine withdrawals—a fate he says is worse than death.
He describes agonizing torture similar to being shocked with a cattle prod (akathisia) and is less preferable to being flogged. He experiences time distortions, hallucinations, tremors, and forgets how to lay down.
Finally he was treated with an adjustment to his meds and/or a rapid drug detox assisted by blood transfusion, most of which occurred while unconcious under the effects of the sedative propofol. I believe some drug tapering was involved as well.
