Consider this: Sleep deprivation is torture. Anyone being held in a condition like this and not getting serious medical attention -- psychological and physiological -- is also torture. The fact that after several months outside the confines of the embassy-cell, he is still in a condition that resembles torture victims is evidence enough of that. It's also very convenient that it looks like this is self-inflicted and "no one can do anything huh?". Any person other than him would be hospitalized immediately.
