Bud I know just what your going threw. I myself was in those same shoes you are in right now a few weeks ago. Just know that it does get better! You should start telling a sense of calmness after the first week. And when you do, you will feel fantasic mentally! Its like this huge boulder is lifted off your shoulders.
Of course you will still need to fight temptation, but your trust me its SO WORTH IT! Feeling sober after so many years of drinking myself is a far better feeling then being smashed everyday!
