At my Preferred IP it’s called the quiet room. I’ve seen several people taken there. They put a Velcro body
Suit around the person and give them a shot of Thorazine. Then they’re taken to the quiet room. All I know about it is there is a plastic sort of bed in there with no sheets or blankets .

I’ve never been restrained but I have been on super close watch before. I tried to hang my self while IP and they made me sit by the desk all day. The followed me to the bathroom and I wasn’t allowed to go anywhere alone. Then I had to sleep in the day room where they could see me all night. -sigh-
It was traumatizing. After that I had to sleep in a camera room
