The point that summed this book up for me is when he is considering how he might retrieve the alcohol from the glass that his own blood has spilled into. Desperate for a drink.
Well it's titled Diary of an oxygen thief for a reason. Seemed like a pretty sound perspective from an immature egotistical alcoholic, ie. very unreliable narrator. Wouldn't spend money buying this, glad I loaned it from the library. As useless as staring into the bottom of a pint glass.
