Yeah working certainly helps me keep away from the booze also.
On my days off it is much harder to stay sober.
I started hitting the club to exercise, watch movies, go shopping at the mall, stop at a coffee/tea joint, go for a walk/bike ride, go to a sporting event, call an old friend with a family who runs the straight route, etc......
If someone calls to hit the bar, I have a ready made excuse, " I have to work", "I am sick and am going to get some sleep", I have to go to ....... or I would go"
I may be initially fibbing but it got me through those days off without being badgered any further so I think I get the pass on it... : )
Find the way to make it through your days off, and next week working will be soo much easier. As time goes by, it gets easier.
Use whatever works my friend!
