Alcohol still has a firm grip on you and for different people, different ways work to take away that grip.
The fact that you left the restaurant to get your ID and then also drove while you had too much should concern you.

Find whatever works for you, but now you can take on the attitude that alcohol isn't an option anymore. Period. Not ever.
What do you think is the reason you keep ending up drinking again?
