"Losing my mind, losing my mind, losing control..."

"Losing my mind, losing my mind, losing control. These fishies in the sea are staring at me. One more spoon of cough syrup. Life's too short to even care at all."
This one is a lyric from the band "Young the Giant", it is called "Cough Syrup". Although, I am about 500% sure that I probably first heard this song from Glee.
