I spent 12 days in a psychiatric hospital last May along with getting on medications(I've been on Celexa, Seroquel, Wellbutrin, Abilify, Lamictal
, Depakote, Lithium
, Metadate, and Trileptal[not all at once]), and it, while at the time I disagreed, and still somewhat do, helped. It kept me safe from harm to myself, and for a while I was stabilized. It's not a cure-all, but it is definitely a valid option, especially in your son's situation, in my opinion.
