Yea I have been inpatient quite a few times, but they keep you longer if you refuse to open up in group was always my experience. It was not a requirement - but the average stay was 3dys, those who did not open up generally found themselves there about a week. So .. I kind of used that to my advantage - if I knew I really needed the help, I just listened n did not open up, if I knew I did not need much help, I opened up. Generally my stays were voluntary. Only one was not. I usually talked my counselor down - but like I said, it took up 90% of the session, very aggravating.
