One theory regarding Poe's death was that it was caused (or accelerated) by Delirium Tremens. The above sentiment adds a bit of credibility to that one, in my humble opinion.
Alcoholics don't own the idea of a hungry heart, (nor are we the sole proprietors of melancholy, hyperbole or being flat out drama queens) but... whatever he is or was, however it all played out, I read that and I think "Poe gets it."
I suppose that if a wildly distorted view of your physical self can be termed body dysmorphic disorder, then it might be said that alcoholics have a kind of social dysmorphic disorder, since our view of ourselves in relation to others is also often wildly distorted and flawed.
An alcoholic mind is no picnic -- there can be a lot going on there.
