I'd go voluntary. You can avoid a lot of drama that way (like police showing up at your door and asking if you're going to cooperate, ambulances, handcuffs, handcuffs in squad cars, handcuffs while be escorted into your final destination hospital... Why do they have to hamdcuff you anyway?! It wasn't like I was going to run away!).

Anyway, voluntary. And do it BEFORE you completely lose your mind.

My first two times were voluntary (well...they involved my husband pretty much dragging me to the ER). Your work will get over it. You don't have to say why you're in the hospital.
