3 different times that I can recall.
I was bored off my ass most of time.
There was one guy that had a hardcore delusion that he was Superman. I got in trouble for having him "prove" to me that he was Superman. I wound up convincing him to try to fly from the top of a bookshelf. Didn't work, on either count. He couldn't fly, but he blamed it on me having kryptonite on me.
The other part that really bugged the crap out me was the AA meetings. I'm not an alcoholic, and the only two substances I'm addicted to are nicotine and caffeine. I don't need the serenity prayer, I don't WANT the serenity prayer, and I object to the institutionalisation of religion as treatment for addictions.
The thorazine was interesting, tho.
