Lyric discussion by cj_17 

Sounds to me that it's about a schizophrenic guy in a relationship with a mentally healthy girl. 'Controlling the agents' with his medication takes an obvious 'toll on his brain'. He's slowly learned proper etiquette for this girl: 'oh, at your favourites [presumably her closest friends] I know now not to swear'. 'The coast of hypnotic' is a place to which they go when no-one else is around, when he can just be himself, idiosyncrasies, eccentricities and all, and he won't let this 'slow decay' of his mind destroy what is possibly the best thing in his life. The line 'I only call them when I know / I don't see them' is probably a reference to visual hallucinations.

Anyway, this is a rather difficult song to interpret. Would be interested in hearing other opinions, because it's really top notch.
