I think the song meaning is pretty obvious: the drugs won't work. It seems that the narrator got out of a relationship he didn't want to get out of, so he is on drugs, but they won't work. Then he keeps encouraging himself that "he'll see your face again", so he knows that he will see the person he lost again. The narrator is obviously suffering serious depression if he is on drugs, because of the relationship, so he just keeps using them as a replacement of the person he lost until he sees that person again.
