Glad you handled the night well but if I were you I wouldn't point a loaded gun at your sobriety to often in the early days. Next time the compulsion might grab hold of you and refuse to let go.
There are several times when I've lost periods of sobriety after being a pub situation, often after having been in the same situation several times without incident.
Not taking away from your achievement of handling yourself well just be careful of testing yourself early on.
