The last thing you need in this situation is to fog yourself and your loved ones with yet another complicating factor! Remember that tomorrow is another day, and if you wake up in hangover and regrets- how do you think you'll cope with the issues then? A drink?
Take a deep breath and look at your self in the mirror. Who you see is you, and that person is the one that will meet the challenges ahead. Hopefully the one you see is sober and ready to deal with it!
Best wishes!
