Poison

The speaker describes an intense attraction that feels exciting but harmful. At first, she lists extreme ways of trying to cope or fill an emotional emptiness, yet nothing compares with the person she desires. The repeated refrain suggests she knowingly returns to this relationship, even as it seems to pull her toward danger.

“Pick my poison” usually means choosing among harmful options; here, the speaker calls the desired person her chosen danger. Images of getting “high” and having someone go “straight to my head” compare love to an intoxicating substance that alters judgment. “Heading straight for the edge” suggests approaching a limit or possible emotional collapse. Calling herself “a lightweight” means she is easily affected, as someone who cannot tolerate much alcohol might be.

The lyrics hold pleasure and pain together: the attraction feels like “bittersweet ecstasy,” and the speaker admits she cannot sleep or think clearly, while insisting that it is “alright.” This may show her accepting the cost because the feeling is so powerful, or trying to convince herself that the situation is manageable. The song does not explain whether the relationship is literally dangerous; the poison and intoxication language can be understood as dramatic metaphors for a consuming desire.
