Your 49 days in, don't blow this. Develop a plan and attack it. You think your lonely now, start drinking again and see what happens. You have to take action. Don't sit around. At 49 days your in a critical stage of your sobriety. It's time to develop new habits. Yes go exercise. Get a hobby. Engage your mind in something. Come here everyday. Just don't drink. The boredom will pass. Trust me it will. Don't squander this 49 day opportunity. That would be tragic and potentially fatal. Hang in there buddy.
