Not sure how it is in other states but in CA no one can force you to commit to a mental hopital. It's under Welfare and Institutions code... (I think).

The only time that they can force is if you committed a felony and institution is part of the plea or sentencing.

I've heard not so good thing about inpatient program.. they limit your access to objects and activities. Food probably suck too. They watch you but on the other hand... you have full access to counselors.
