When you finally quit doing something problematic, the flash of hope is enough to motivate you for a while, but soon the suffering of going without replaces that hope with the dread of a joyless future.
This is important: If you surrender your stopping power to today's demon, you'll be vulnerable to every demon that comes along in the future.
Cry, scream, sleep all day, but hold on to your power to stop like your life depends on it, because it does.
