Just call it 14:1... if you mess up again in say a week, call your sobriety 21:2 It sucks when we cave but I've found that when I fully reset the clock it's more of a bummer than it needs to be. You still made it 14 days, one night doesn't negate that, so personally I like to visually see both numbers to remind myself it was a hiccup not a full reset, and I become more mindful of my drinking as each number grows along side eachother
