30 days is a HUGE milestone! Once somebody has been sober for a few years, the compulsion to drink goes away one day at a time. I remember when I was new to sobriety, each day was plagued by passing thoughts about drinking. In my mind, the newly sober people display an amazing degree of self-control. It can be damned DIFFICULT at first, but keep hanging on. Believe me, you will see your life & moods get better. Way to go!
