My doctor told me that I had to come off the medication that I was on gradually though and it was
only an antidepressant. Whether they tell you that it's addictive or not seems like a moot point. Stop taking it abruptly and you're going to get an abrupt change in brain chemistry. That may be the definition of a chemically induced psychosis but it's also an example of someone that neglected to follow their doctor's orders and suffered the consequences of it.
It's not that I don't believe you. I do think though that people are responsible for taking their medication properly. Unfortunately the mentally ill tend not to be the most disciplined of people. I knew one girl for instance that said that she didn't have enough hours in the day to take her medication three times a day, so she just took everything at once. This was a person that didn't even have a job, so kind of a BS excuse.
