I'm doing this solo too so I can offer some insight there. When each day comes and I think about drinking I say to myself. Well I made it through 21 days before without drinking. I'm sure I can do it again. I just go one day at a time and hope it will get easier. My best advice is stay away from temptation in the beginning. You probably have more spare cash without drinking so go out to eat at a nice place. Work out a new routine so the new places arent reminding you of being drunk like the old haunts do. Good luck.
