I would stay away from drinking situations, even if it's lunch with friends. In the beginning it is just too draining to have to struggle with the addictive voice. You will eventually calm the mind, and be more in control, but until then, work on your sobriety in safe places. Next time, before you sit down with friends, make the commitment to yourself that you will not drink, because we all know it's not just one drink. It just makes it more real. You can do it!
