Sorry, nota—I know I've had vacations that caused more stress than they cured.
Maybe you can cut yourself some slack, make the goal less about making everything better, more about just doing what you can and letting go of the rest?
Have you tried playing the drinking forward, picturing how it would be to wake up the next day to realize what you had done, and how it hadn't changed anything?
See how it feels tomorrow. You can do it!
