酒喝多了自然会醉心伤透了自然会疼
[jiŭ hē duō le zì rán huì zuì xīn shāng tòu le zì rán huì téng]
A metaphorical expression for dealing with personal pain and healing process using drink-induced sleepiness and heartbreak as analogies. When people get too much liquor inside them - drunkenness comes naturally; likewise when hurt too deeply emotionally, pain becomes inevitable and must course through your system until you've 'slept off' or 'recuperated' enough.
