Endlesspatience, good that you are at work and there's no booze around. But be beware of evening hours when you head home and left alone with your thoughts. Make some plan that will enable you to avoid temptations. Anything to keep you from drinking. Any ideas what you can do?
I have no experience related specifically to your situations, but I can tell that drinking make us do absolutely crazy things like we don't own our mind, though we are left with aftermath of this.
I think it's important to be honest with yourself now - do you fell you are not interested any more and this just happened because you were drunk? If so then fight for your sobriety with all the means necessary. It will save you all these troubles.
Stay strong.
