As soon as the doctors got their order for involuntary treatment in November 2015, they cornered my friend and injected her with a time-release version of haloperidol, then released her to her mother's house.
A day and a half later her mom called the psychiatrists, who said to take my friend to a real ER. My friend told the real doctors at the real ER that she was NOT suicidal. She told me how the haloperidol had 'hit her like a truck', and she tried everything she could think of to counteract the agony: alcohol, cocaine, heroin, dextromethorphan (aka cough syrup), etc.
All the anti-dopamine drugs are terrible. Some of the second-generation drugs that are forced on people are much worse than plain old haloperidol. The poor doctors are just implementing their training. Tragic.
My observation is that agony-inducing drugs are not actually helpful for substance abuse.
