Call it a 30-day stint, if that's what helps you through for now. But Sobriety is life long. It requires change in body and soul. Most of us take it one day at a time for good reason; today is right now, it's all I have, so why worry about tomorrow? I'll just make myself crazy.
You are going to have to want to live Sober more than want to drink. Good luck
