“A book is open in front of me and this is what it has to
say about the symptoms of morphine withdrawal:

'... morbid anxiety, a nervous depressed condition,
irritability, weakening of the memory, occasional
hallucinations and a mild impairment of consciousness
...'

I have not experienced any hallucinations, but I can
only say that the rest of this description is dull, pedestrian
and totally inadequate.

'Depressed condition' indeed!

Having suffered from this appalling malady, I hereby enjoin
all doctors to be more compassionate toward their
patients. What overtakes the addict deprived of morphine
for a mere hour or two is not a 'depressed condition': it is
slow death. Air is insubstantial, gulping it down is useless
... there is not a cell in one's body that does not crave
... but crave what? This is something which defies analysis
and explanation. In short, the individual ceases to exist:
he is eliminated. The body which moves, agonises and
suffers is a corpse. It wants nothing, can think of nothing
but morphine. To die of thirst is a heavenly, blissful death
compared with the craving for morphine. The feeling must
be something like that of a man buried alive, clawing at the
skin on his chest in the effort to catch the last tiny bubbles
of air in his coffin, or of a heretic at the stake, groaning and
writhing as the first tongues of flame lick at his feet.

Death. A dry, slow death. That is what lurks behind
that clinical, academic phrase 'a depressed condition'.”
