to burn the candle at both ends (to do things in excess, to engage in too much work or too much pleasure (including spending money), or both)
“C'est, à ce qu'on assure, un fameux lapin! il roule sur l'or! il mène avec lui trois maîtresses et son cuisinier! Tous ces grands artistes brûlent la chandelle par les deux bouts; il leur faut une existence dévergondée qui excite un peu l'imagination.” — From what I hear, he's a regular dog; he's rolling in money; he's taking three mistresses and a cook along with him. All these great artists burn the candle at both ends; they require a dissolute life, that stirs the imagination to some extent.
