If you don't mind, could you say a bit more about the psychotic break? The closest thing from my own experience is being told that I thrashed around a lot while coming out of post-surgery anesthesia, but I have no memory of it.
I remember having a sundowner, talking with my family and slowly getting more and more irritated about some minor conversational bit someone said.
I clearly remember starting to get louder and more aggressive and then I blacked out. I woke up in a pool of my own sweat several days later wondering what had happened.
People talked to me about what happened I piece together bits and pieces floating around in a red haze and having a human pile on top of me.
In retrospect the weirdest part was how readily they accepted I was sane again.
General anesthesia often has this effect on both sides, because muscle tone is lost late in induction and regained early in recovery. If you've been surprised to find yourself wrapped snugly in a sheet just before being put under, this is why.
It's not related to the sort of mental effects of antimalarials mentioned in GP's comment.
