I had a few moments like that in my career. I managed to sneak a couple of drinks into what was a bad day and it felt better. But, then, the allergy was triggered. I went to bed and woke up the next day with physical cravings and intense mental obsession. So much for getting away with it!
Have you considered what feeling good about "getting away with it" is going to do for your next challenging moment? When life is pummeling you down to the pavement, you might refer to this memory and think: it went well. I did that too, and, what inevitably happened was that it never went well the next time!
