Hi HMS,
Welcome back and congrats for being sober, i ve been in similar situation of yours, Even after being sober for a month , Alcohol carving might lead us to drinking we start it saying just 1 peg which results ending up in our previous condition. let me phrase u a sentence, " Cigarette bud can cause forest fire ". so even 1 drop of alcohol will take us back, so be strong and make up that you never drink again... all the best.
