porphyria
"I have strugged a lot from psychosis worsened by Acute Intermittent Porphyria (AIP)/Variegate Porphyria(VP). Originally, it was thought that I was a High-Functioning Schizophrenic, with various other labels. Thorazine, when it was first used on me, was to calm me down when I was on the brink of a Blackout Rage, effectively knocking me out, and for a while after I woke up, the hallucinations were surprisingly minimized.
Once released from that facility, I was on a treatment haitus. Later, I was prescribed Thorazine again. It didn't make it all go away. But it helped take the edge off and help me maintain control."
