Hummm, just don't make a big deal out of it. I do, however, caution you not to rescue her from natural consequences to her actions. (If she has to rest due to her being out drinking.) She didn't seem too concerned she had no memory after drinking. You may not be able to do much about that right now, but on the other hand, don't swing the other way by comforting/helping so that she can continue without taking responsibility.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
