Metaphor for the soothing effect that results from the use of an addict's drug of choice - Gregory Isaacs popularized this term with his 1982 reggae hit "Night Nurse"
Night nurse
Only you alone can quench this Jah thirst
My night nurse, oh gosh
Oh the pain it's getting worse
I don't wanna see no doc
I need attendence from my nurse around the clock
'Cause there's no prescription for me
She's the one, the only remedy
