I live in an European country, here it is really hard to legally force someone to take meds.... But you know, one of my IP pdoc just told me if I didnt take meds he wouldn't allow me to go outside during evenings (It wasnt a closed unit, almost everyone was allowed to go out for 3-4h from 4:00pm to 8:00pm), I explained him I was taking care of a ferret that would starve if I wasnt allowed to go home (I want to point out I lived in front of the hospital... Literally in front of....).

His answer was "Let it starve, then".
