The serpent sleeps in your stomach,
coiling, uncoiling
with every breath.
He slithers in circles, snaking
round and round,
up and down,
through and through.
You cannot sleep; you lay awake;
you feel him within
yourself, winding.
Tightly clutching your stomach
you reach into your throat
and gag; vomit.
Out the serpent slides, down the drain;
at last he’s gone,
but you still feel sick.
