I have always liked this saying. It puts it very simply for me as a reminder that nothing is better than being sober. There is not a single thing that isn't better in my life now.
This phrase makes a comparison for me- is one night of (x fun or whatever) worth losing my sobriety? Is going out again worth losing my relationship? Is it worth losing my peace of mind and self-respect? And so on.
I understand certain phrases grate- I have always hated "romancing the drink" probably bc my mom would say it. And that is also not one of my problems (right now).
As they say, take what works and leave the rest. I don't find focusig on the things that annoy me to be helpful. And what's helpful and useful - and sometimes constructively challenging- is all I need to focus on!
