"Poison Was the Cure" is the fifth track of Megadeth album Rust in Peace. The title seems to suggest that a medicine that cured a disease is now a poison. But the lyrics drifts farther from that. It is about serpent and dragon in his body that would make him to end life in the gallows.
I miss the warm embrace I felt First time you touched me Secure and safe in open arms I should have known you'd crush me A snake you were when we met I loved you anyway Pulling out your poisoned fangs The venom never goes away Serpent swims free in my blood Dragons sleeping in my veins Jackyl speaking with tongue Roach egg laying in my brain Once stalked beneath your shadow Sleepwalking to the gallows I'm the sun that beats your brow in 'til I finally threw the towel in Never knowing if I'd wake up in a Whirlpool got redundant My brain was just some driftwood In a cesspool I became dead From a rock star to a desk fool Was my destiny someone said Love's a tide pool Taste the waters life's abundant Taste me
