You watched an ongoing diagnosis, over a six month period? By a “biochemical psychiatrist,” no less. Was he islamic, by chance of circumstance?
Of course not. Actually he was complaining that after all that work, a patient would go on a bender, which would so scramble their brain chemistry that it would set them back months. He then went into an extended rant against alcohol.
Importantly, this was in the 1980s, in which the number of medicines available was just a fraction of the number in use today. And some were “shotgun” solutions to “BB gun” problems, but were desperately needed. So a lot of it was experiment and guess work.
