Steve, I've always found those liquor store times maddening but also in a way a blessing... I think about all the times I raced out of a class or whatever I was doing in order to get there in time, but I also relish the fact that they close and come 9pm I would feel the weight of the decision taken off my back!
Just like driving past the liquor stores you used to stop at. Coming up to it, you feel overwhelming anxiety that you think is only going to go away if you give in to the craving and stop in.. but then you keep driving past it, and the crushing feeling lets up.
They're actually blessings in disguise when they show you that you can be stronger than the urge.
