Do you know WHY are you being impulsive? Like... needing some excitement, feeling that you need to this right now, because world might end tomorrow... distracting yourself from other thoughts? Or maybe it's unconsious wanting to harm somebody?

and no offense, but what you posted you should fired that pnurse long time ago... she treated you as a slot machine. Do you have somebody to work with on the emotional aspects of your impulsivness.
