Nating, I'm glad you are doing well.
I wouldn't know how to answer specifically why the urge seemed to fall on you at that particular time, because there are multiple plausible reasons. I'm not a statistical expert or expert in general on this, but I suppose these episodes would decrease in frequency as time goes on.
All those negative things you listed and more will be good for you to remember. For some people, it's unfortunately not enough. I like to think that time passing without alcohol allows for a peace to exist inside, and that kind of thinking has worked for me, because I don't want to give it up.
