On last weeks' episode of the tv show 'Elementary' . . .?

they played a song at the very end, where she's waiting for Liam (Lucy Lius ex) to meet her at some rehab place she's helped him get into . . it had something to do with . . "when the drugs stop . . . . hope you got a minute" or something like that. Kept playing it over, but couldn't get it. I tried youtube w/what lyrics I had. Does anyone out there know what the song was?? Or have more lyrics???? Thanks!!
