Hi Change4good.
Sobriety takes practice. Hopefully, it won't be more practice than active effort but the fact that you posted is telling. You want this, for good. I think we all feel like maybe something will be different once we get away from the alcohol for a while and choose to drink. It takes a few stumbling blocks to realize that all roads lead back to quitting.
Today is a new day for you. Imbed last night into memory and use it when you consider picking up. As much as you're going to feel bad today it's important to not let that leave your mind.
