I was pumped with so many drugs, and my guess is that they interacted with one another and produced undesireable side-effects.
Hair loss, shrunken penis, memory loss etc.
When you first are admitted to any psychotic ward, you line up and are given a massive dosage of tranquilizers by the head nurse. No one checks you beforehand and tries to determine what you are already taking, medication wise, so often you have drugs upon drugs upon drugs mixing with one another. Then, every morning or second morning, you see the psychiatrist on call. Each psychiatrist will give the nurses orders to inject you or force you to take more medication and rarely do they consult with the previous doctor as to what was prescribed for you beforehand. They don't check each patients records because that is time consuming and they don't care anyways. So, you are basically just one big SPONGE of human tissue and while you are there - 10 days, 14 days, 30 days, 90 days or longer - you will be pumped and pumped with more drugs.
They want you sedated, so you are easy to manage and the hospital can make SUPER EASY MONEY. The more drugs they give you, the more they can bill the government for your 'treatment'. Overall, the more money the psychiatric patients bring in and the easier they are to control, the more money the hospital makes in the long run.
All the mixing of drugs, and the entire environment in general, isn't condusive to 'getting better'.
Just like the education racket, public mental health facilities aren't designed to serve the public well.
