You go on one day at a time, sarahdub. Use this incident as a reminder when thoughts of "my drinking wasn't so bad" start creeping in. But don't beat yourself up too bad--there's a better life waiting for you in true recovery.
Remember that you don't have to take that first drink today no matter what. And as long as you don't take that first drink, you can't take the second or third or tenth drink that will almost inevitably follow.
Wishing you the best today...
